Hi, To create a custom ISO, download the ISO you want to use as your base, use tar to extract the ISO into a new directory, make the changes you want and then run mkisofs -V FreeBSD9 -J -R -b boot/cdboot -no-emul-boot -o ../freebsd_custom.iso . from the new directory. That will create a bootable CD. What I did when making a custom install CD for my server (it's 1000s of miles away in a datacenter) was a slightly different approach. I created a sparse file (sparse to save on disk space) the exact size of my server harddrive on my running BSD box, used mdconfig to give me a md device and pointed VirtualBox at it. Within a VBox session, I did a normal install (manually created the ZFS filing systems), made all the config changes I wanted, installed the apps I wanted then shut the VBox session down. I DD-ed in the md device and piped it to bzip2, creating a bz2 file. Added the bz2 file to the custom BSD install ISO and modified /etc/rc.local file to un-bzip the bz2 file, pipe it to mbuffer (so the opperator could see something was happening) and write the output to the harddrive, popping the reset line when complete. When the server restarted, it was configured with all the right user accounts, ip addresses, nameserver settings etc. Just my 2 pence worth...

Is pkgng supposed to upgrade a dependency of a locked package?
I am using pkgng 1.1.4_1 on RELENG_9 (r252725), operating on a local repo I maintain using poudriere 3.0.4. Recently, I wanted to upgrade all packages on a client except two whose update I want to defer for now as they potentially impact locally-developed applications. I figured I would use the pkgng lock functionality on those two packages (apache-solr and py27-Jinja2) to prevent them from being updated. I ran pkg upgrade on the client and, as expected, the locked packages weren't upgraded. However, I was surprised to see that packages upon which the locked packages depended were upgraded. Unless I'm misunderstanding something, the man page for pkg-lock states this should not happen: = The impact of locking a package is wider than simply preventing modifica- tions to the package itself. Any operation implying modification of the locked package will be blocked. This includes: [[...]] o Deletion, up- or downgrade of any package the locked package depends upon, either directly or as a consequence of installing or upgrading some third package. = In my case, the following dependencies of apache-solr were updated, even though apache-solr is locked: java-zoneinfo: 2013.c - 2013.d; libXi: 1.7.1_1,1 - 1.7.2,1; libXrender: 0.9.7_1 - 0.9.8; and openjdk: 7.21.11 - 7.25.15. In the case of the locked py27-Jinja2, these dependencies were updated: gettext: 0.18.1.1_1 - 0.18.3; and py27-MarkupSafe: 0.15 - 0.18. Dependency information in the two locked packages was updated to reflect these new, upgraded dependencies. Is this a bug, or am I misreading the man page?

When I first started dealing with Unix professionally (1995, I started playing with Unix-like OSes almost 10 years earlier) I was taught that each Unix command does one thing and does it well.

With the popularization of Linux I see many movements towards a dumbing down of the OS, making it behave more like more common OSes, even if those changes make it less robust and flexible. One of the reasons I choose FreeBSD over Linux in many cases is that FreeBSD is closer to the roots of Unix in terms of keeping things simple and reliability being more important than convenience.

Re: swap partition leads to instability?
On May 29, 2013, at 3:52 PM, jb jb.1234a...@gmail.com wrote: Yes, there is some confusion about the diff, if any, between paging and swapping. Paging - copying or moving pages between physical memory (RAM) and secondary storage (e.g. hard disk), in both directions. Swapping - nowdays is synonymous with paging. You say that FB supports both, Linux supports paging only. Well, Linux utilizes swap space as part of virtual memory. So, can you elaborate more on that - what is the essence of the diff, why should I avoid the term swapping when referring to Linux, assuming VMM systems on both ? When I started working professionally with Unix systems in 1995, I was taught that paging was the process of copying least used pages of RAM onto disk so that the RAM could be freed if the system needed more RAM. Swapping was the process of moving an entire program from RAM to disk in order to free up RAM. In other words, a process can be swapped out and placed on disk until it comes up to run again, at which point it can be swapped in and executed. I think that much of the confusion comes from the use of the SWAP device by the PAGING system. When the concept of paging came about, it just used the already existing SWAP space to store it's paged out pages of memory. On the systems I worked on at the time (SunOS / Solaris), paging was a sign of pressure on the physical memory (RAM) of a system, swapping was a sign of _severe_ physical memory pressure. This was a time when we configured 2 to 4 times the amount of physical RAM as SWAP space. RAM was very expensive and hard drives just expensive :-) It was common on a normally operating system to see the page scanner* running up to 100 times per second. A scan rate of over 100 was considered a sign of pressure on RAM that needed to be addressed, any SWAPing was considered a sign that the system needed more physical RAM. Today RAM is so cheap that _any_ paging is often considered bad and an indication that more Ram should be added. *Solaris Page Scanner: This is a kernel level process that wakes up, examines the amount of free RAM, and takes action based on that value. The thresholds are all dynamic and based on the amount of RAM in the system. Above a high water mark the scanner does nothing. As the amount of free RAM drops, various pages of RAM are copied to SWAP space and the RAM freed. Eventually, if the amount of free Ram falls low enough, even parts of the kernel will be paged out. This is very bad and can lead to a system thrashing where it spends the vast majority of it's time just paging in and out and not actually getting anything done. -- Paul Kraus Deputy Technical Director, LoneStarCon 3 Sound Coordinator, Schenectady Light Opera Company ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Without dedup, the requirements are more modest. The rule of thumb for DeDupe is 1GB physical RAM for every 1TB of capacity. The issue is that the DeDupe metadata table must live in the ARC for good performance. The discussion I have seen on the ZFS lists indicates that L2ARC is not really adequate for this, so adding cache devices (SSD's) don't really help. On the other hand, you can use ZFS without DeDupe with as little as 2GB of total system RAM (depending on what else the system is doing).

This does NOT scale with size of drive, it is the same for all drives with an uncorrectable error rate of 10^-15 bits. So if you read the entirety of a 1 TB drive 114 times or a 4 TB 29 times you get the same result. But this is a statistical probability, and some drives will have more (much more) uncorrectable errors and others will have less (much less), although I don't know if the distribution falls on a typical gaussian (bell) curve. -- Paul Kraus Deputy Technical Director, LoneStarCon 3 Sound Coordinator, Schenectady Light Opera Company ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Yes, this RAID is good, but unless you use SSD disks to boost performance and a lot of RAM the hardware raid should be more reliable and mush faster. Why will the hardware raid be more reliable ? While hardware raid is susceptible to uncorrectable errors from the physical drives (hardware raid controllers rely on the drives to report bad reads and writes), and the uncorrectable error rate for modern drives is such that with high capacity drives (1TB and over) you are almost certain to run into a couple over the operational life of the drive. 10^-14 for cheap drives and 10^-15 for better drives, very occasionally I see a drive rated for 10^-16. Run the math and see how many TB worth of data you have to write and read (remember these failures are generally read failures with NO indication that a failure occurred, bad data is just returned to the system). In terms of performance HW raid is faster, generally due to the cache RAM built into the HW raid controller. ZFS makes good use of system, RAM for the same function. An SSD can help with performance if the majority of writes are sync (NFS is a good example of this) or if you can benefit from a much larger read cache. SSDs are deployed with ZFS as either write LOG devices (in which case they should be mirrored), but they only come into play for SYNC writes; and as an extension of the ARC, the L2ARC, which does not have to be mirrored as it is only a cache of existing data for spying up reads. I didn't get if you want to use the system to dual boot Linux/FreeBSD or just to share FreeBSD space with linux. But I would advise you to go with option 1 - you will get most of the system and obviously you don't need zpool with raid, as your LSI controller will do all the redundancy for you. Making software RAID over the hardware one will only decrease performance and will NOT increase the reliability, as you will not be sure which information is stored on which physical disk. If stability is a MUST, then I will also advise you to go with bunch of pools and a disk designated as hot spare - in case some disk dies you will rely on the automation recovery. Also you should run monitoring tool on your raid controller. I think you misunderstand the difference between stability and reliability. Any ZFS configuration I have tried on FreeBSD is STABLE, having redundant vdevs (mirrors or RAIDzn) along with hot spares can increase RELIABILITY. The only advantage to having a hot spare is that when a drive fails (and they all fail eventually), the REPLACE operation can start immediately without you noticing and manually replacing the failed drive. Reliability is a combination of reduction in MTBF (mean time between failure) and MTTR (mean time to repair). Having a hot spare reduces the MTTR. The other way to improve MTTR is to go with smaller drives to recede the time it takes the system to resilver a failed drive. This is NOT applicable in the OP's situation. I try very hard not so use drives larger than 1TB because resilver times can be days. Resilver time also depends on the total size of the the data in a zpool, as a resolver operation walks the FS in time, replaying all the writes and confirming that all the data on disk is good (it does not actually rewrite the data unless it finds bad data). This means a couple things, the first of which is that the resilver time will be dependent on the amount of data you have written, not the capacity. A zppol with a capacity of multiple TB will resilver in seconds if there is only a few hundred MB written to it. Since the resilver operation is not just a block by block copy, but a replay, it is I/Ops limited not bandwidth limited. You might be able to stream sequential data from a drive at hundreds of MB/sec., but most SATA drives will not sustain more than one to two hundred RANDOM I/Ops (sequentially they can do much more). You can also set copies=2/3 just in case some errors occur, so ZFS can auto0repair the data. if you run ZFS over several LUNs this will make even more sense. -- Paul Kraus Deputy Technical Director, LoneStarCon 3 Sound Coordinator, Schenectady Light Opera Company ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

I believe the copies=2 and copies=3 option exists to enable ZFS to self heal despite ZFS not being in charge of RAID. If ZFS only has a single LUN to work with, but the copies=2 or more option is set, then if ZFS detects an error it can still correct it. Yes, but …. What the copies=n parameter does is tell ZFS to make that many copies of every block written on the top level device. So if you set copies=2 and then write a 2MB file, it will take up 4MB of space since ZFS will keep two copies of it. ZFS will attempt to put them on different devices if it can, but there are no guarantees here. If you have a single vdev stripe and you lose that one device, you *will* lose all your data (assuming you did not have another backup copy someplace else). On the other hand, if the single device develops some bad blocks, with copies=2 you will *probably* not lose data as there will be other copies of those disk blocks elsewhere to recover from. From my experience on the ZFS Discuss lists, the place people seem to use copies=more than 1 are on laptops where they only have one drive and copies=more than1 is better than no protection at all, it is just not complete protection. This option is a dataset option, is inheritable by child datasets, and can be changed at any time affecting data written after the change. To get the full benefit you'll therefore want to set the option before putting data into the relevant dataset. You can change it any time and it will only effect data written from that point on. This can be useful if you have both high value data band low value and you can control when each is written. For example, you leave copies=1 for most of the time, then you want to save your wedding photos, so you set copies=3 and write all the wedding photos, you then set copies=1. You will have three copies of the wedding photos and one copy of everything else. -- Paul Kraus Deputy Technical Director, LoneStarCon 3 Sound Coordinator, Schenectady Light Opera Company ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

On May 14, 2013, at 12:10 AM, Shane Ambler free...@shaneware.biz wrote: When it comes to disk compression I think people overlook the fact that it can impact on more than one level. Compression has effects at multiple levels: 1) CPU resources to compress (and decompress) the data 2) Disk space used 3) I/O to/from disks The size of disks these days means that compression doesn't make a big difference to storage capacity for most people and 4k blocks mean little change in final disk space used. The 4K block issue is *huge* if the majority of your data is less than 4K files. It is also large when you consider that a 5K file will not occupy 8K on disk. I am not a UFS on FreeBSD expert, but UFS on Solaris uses a default block size of 4K but has a fragment size of 1K. So files are stored on disk with 1K resolution (so to speak). By going to a 4K minimum block size you are forcing all data up to the next 4K boundary. Now, if the majority of your data is in large files (1MB or more), then the 4K minimum black size probably gets lost in the noise. The other factor is the actual compressibility of the data. Most media files (JPEG, MPEG, GIF, PNG, MP3, AAC, etc.) are already compressed and trying to compress them again is not likely to garner any real reduction inn size. In my experience with the default compression algorithm (lzjb), even uncompressed audio files (.AIFF or .WAV) do not compress enough to make the CPU overhead worthwhile. One thing people seem to miss is the fact that compressed files are going to reduce the amount of data sent through the bottle neck that is the wire between motherboard and drive. While a 3k file compressed to 1k still uses a 4k block on disk it does (should) reduce the true data transferred to disk. Given a 9.1 source tree using 865M, if it compresses to 400M then it is going to reduce the time to read the entire tree during compilation. This would impact a 32 thread build more than a 4 thread build. If the data does not compress well, then you get hit with the CPU overhead of compression to no bandwidth or space benefit. How compressible is the source tree ? [Not a loaded question, I haven't tried to compress it] While it is said that compression adds little overhead, time wise, Compression most certainly DOES add overhead in terms of time, based on the speed of your CPU and how busy your system is. My home server is an HP Proliant Micro with a dual core AMD N36 running at 1.3 GHz. Turning on compression hurts performance *if* I am getting less than 1.2:1 compression ratio (5 drive RAIDz2 of 1TB Enterprise disks). Above that the I/O bandwidth reduction due to the compression makes up for the lost CPU cycles. I have managed servers where each case prevailed… CPU limited so compression hurt performance and I/O limited where compression helped performance. it is going to take time to compress the data which is going to increase latency. Going from a 6ms platter disk latency to a 0.2ms SSD latency gives a noticeable improvement to responsiveness. Adding compression is going to bring that back up - possibly higher than 6ms. Interesting point. I am not sure of the data flow through the code to know if compression has a defined latency component, or is just throughput limited by CPU cycles to do the compression. Together these two factors may level out the total time to read a file. One question there is whether the zfs cache uses compressed file data therefore keeping the latency while eliminating the bandwidth. Data cached in the ZFS ARC or L2ARC is uncompressed. Data sent via zfs send / zfs receive is uncompressed; there had been talk of an option to send / receive compressed data, but I do not think it has gone anywhere. Personally I have compression turned off (desktop). My thought is that the latency added for compression would negate the bandwidth savings. For a file server I would consider turning it on as network overhead is going to hide the latency. Once again, it all depends on the compressibility of the data, the available CPU resources, the speed of the CPU resources, and the I/O bandwidth to/from the drives. Note also that RAIDz (RAIDz2, RAIDz3) have their own computational overhead, so compression may be a bigger advantage in this case than in the case of a mirror, as the RAID code will have less data to process after being compressed. -- Paul Kraus Deputy Technical Director, LoneStarCon 3 Sound Coordinator, Schenectady Light Opera Company ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

From discussion on the zfs-discuss lists (both the old one from OpenSolaris and the new one at Illumos) the only issue with 4K sector drives is mixing 0.5K sector and 4K sector drives. You can tunes the zpool offset to handle 4K sector drives just fine, but it is a pool wide tuning. http://zfsday.com/wp-content/uploads/2012/08/Why-4k_.pdf has some 4K background, and the only mention I see of compression and 4K is that you may get less. But… you really need to test your data to see if turning compression on is beneficial with any dataset. There is noticeable computational overhead to enabling compression. If you are CPU bound, then you will get better performance with compression off. If you are limited by the I/O bandwidth to your drives, then *if* your data is highly compressible, then you will get better performance with compression on. I have managed large pools of both data that compresses well and data that does not. http://wiki.illumos.org/display/illumos/ZFS+and+Advanced+Format+disks discusses the issue and presents solutions using Illumos.

With a 4K minimum block size (which is what a 4K sector size implies), a file less than 4KB will not compress at all. While ZFS does have a variable block size (512B to 128KB), with a 4K minimum black size (just like with any fixed block FS with a 4KB block size), small files take up more pace than they should (a 1KB file takes up an entire 4KB block). This ends up being an artifact of the block size and not ZFS, any FS on a 4K sector drive will have similar behavior. I leave compression off on most of my datasets, only turning it on on ones where I see a real benefit. /var compresses vert well (I turn off compression in /etc/newsyslog.conf and let ZFS compress even the current logs :-), I find that some VM's compress very well, media files do NOT compress very well (they tend to already be compressed), generic data compresses well, as do scanned documents (uncompressed PDFs).

It was a statement, and luckily I was partially wrong, as Vladislav did made
what he wanted to.
However, last time I checked there were no such easy ways to decrease zpools
Correct, there is currently no way to decrease the size of a zpool. That would
require a defragmentation utility, which is on the roadmap as part of the
bp_rewrite code enhancement (and has been for many, many years :-)
or increase/decrease UFS partitions.
Or grow mirrored ZFS as easily as single zpool.
This one I do not understand. I have grown mirrored zpools many times. Let's
say you have a 2-way mirror of 1 TB drives. You can do one of two things to
grow the zpool:
1) add another pair of drives (of any size) as another top level vdev mirror
device (you *can* use a different type of top level vdev, raidZ, simple, etc,
but that is not recommended for both redundancy and performance predictability
reasons).
2) swap out one of the 1 TB drives for a 2 TB (zpool replace), you can even
offline one of the halves of the mirror to do this (but remember that you are
vulnerable to a failure of the remaining drive during the resolver period), let
the zpool resolver, then swap out the other 1 TB drive for a 2 TB. If the auto
expand property is set, then once the resolver finishes you have doubled your
net capacity.
Or (killer one) remove added by mistake vdev from zpool ;)
Don't make that mistake. Seriously. If you are managing storage you need to be
double checking every single command you issue if you care about your data
integrity. You could easily make the same complaint about issuing an 'rm -rf'
in the wrong directory (I know people who have done that). If you are using
snapshots you may be safe, if not your data is probably gone.
On the other hand, depending on where in the tree you added the vdev, you may
be able to remove it. If it is a top level vdev, then you have just changed the
configuration of the zpool. While very not supported, you just might be able,
using zdb and rolling back to a TXG before you added the device, remove the
vdev. A good place to ask that question and have the discussion would be the
ZFS discuss list at illumos (the list discussion is not limited to illumos, but
covers all aspects of ZFS on all platforms). Archives here:
http://www.listbox.com/member/archive/182191/sort/time_rev/
Of course I'm not talking about real hw, rather virtual one.
Doesn't matter to ZFS, whether a drive is a physical, a partition, or a virtual
disk you perform the same operations.
If you happen to point me somewhere to have such task solved I'd be much
appreciated.
See above :-) Some of your issues I addressed above, others are not there (and
may never be).

gettext-0.18.1.1 issues

I can watch the activity lights on the disks and it cranks away for a minute or so, then stops for a minute, then cranks for a minute, and so forth. If I do a zpool status while it's stopped, the zpool waits until the I/O resumes, and a ^T shows it waiting for zio-io_cv. I'm running FreeBSD 9.1, amd64 version, totally vanilla install on a mini-itx box with 4GB of RAM. The root/swap disk is an SSD separate from the zfs disks. When the disks are active, top shows about 10% system time and 4% interrupt. When it isn't, top shows about 99.8% idle. The server isn't doing much else, and nothing else currently touches the disks. (They're for remote backup of a system somewhere else, and I have the backup job turned off until resilvering completes.) Under 9.0 I had some external drives attached via USB and saw truly terrible I/O performance. I moved them to ESATA and it got much better. Unfortunately, my external exclosure has a SATA port expander as I need to talk to 4 external drives.

How to I recapture the remaining 2+TB of space that's not being used? The easiest way to use your extra space is to not adjust one of those 5 BSD partitions, but instead create a new DOS partition (mfid0s2 as previously discussed above). However, if you *really* want to grow an existing BSD partition, this can be done (very carefully). I'm all for taking the easy way out. :-) First, you'll want to save the output of disklabel -r mfid0s1 to a text file. Next, you'll have to re-fdisk mfid0 so that the first slice covers the entire disk. Of course, re-mastering the slices does not affect the data, but it _will_ wipe out the BSD partition map (the disklabels; in other words, after

On Jan 27, 2013, at 8:36 PM, Shane Ambler wrote: I recall reading that using partitions for zfs on FreeBSD was as good as full disks. For a boot zpool we need to at least have a partition for the boot-code and one for zfs preventing the use of a full disk. I have been using ZFS with GPT partitions with no issues. I have NOT compared performance between whole disk and partitioned, which is where the difference in Solaris arises (ZFS makes better use of the physical drive's write cache). ZFS is meant to be compatible between different endian systems (x86 and sparc) From what I have read and heard it sounds like zpools are expected be compatible between different OS's as well - as far as zpool versions are compatible - but I do expect it would depend on the partition tables being readable - while full disk usage should work I would also think GPT is compatible. OSX 10.5 (x86 and ppc) included a read-only zfs kext (before Apple canned the project) so it must have been able to read Solaris or FreeBSD created zpools which does indicate a fairly high level of compatibility. The target OS must be able to read the partitioning scheme used. I am not aware of Solaris / OpenSolaris / Illumos being able to read GPT partitions, but it has been over 6 months since I played with any of them. I believe the way ZFS marks disks/partitions with the zpool data is so that the zpools can be recognised between systems and controllers - it would be interesting to know if and under what conditions a zpool can be accessed, both between different FreeBSD machines as well as the possibility of reading on a Solaris/Indiana machine. Anyone have the resources to test? When you give ZFS the whole disk, it writes an EFI-like label on the drive and makes us of one partition for the ZFS data. So there *is* a form of partitioning at the lower most layer, it is just *not* user managed partitioning. -- Paul Kraus Deputy Technical Director, LoneStarCon 3 Sound Coordinator, Schenectady Light Opera Company ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Note the rootpool/do-not-remove daatset. This has a quota and reservation of 1 GB. It's purpose is to permit recovery in case the zpool is accidentally filled. ZFS requires *some* free space top process file / directory remove operations. If the zpool is completely filled you will NOT be able to remove anything to free up space. By having a dataset with a quota and reservation of 1 GB, that space is already marked as used so it will not be allocated. If the remainder of the zpool fills, then you can quiet the system (so running processes don't steal the space you are about to free up), change the quota / reservation (I like going down to 512 MB), and then remove some files / directories to free up space. Note that the zpool itself (rootpool) is NOT used as a dataset and is NOT mounted. My experience with ZFS under Solaris taught me that while you *can* use that dataset, if you have any child datasets (and any other datasets created will, by definition, be children of the rootpool) you will end up with hierarchical datasets. This means that future operations on datasets will have to take place in very specific order (such as mounting and un mounting). By avoiding hierarchical datasets (that are actually used) you avoid that complexity. -- Paul Kraus Deputy Technical Director, LoneStarCon 3 Sound Coordinator, Schenectady Light Opera Company ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

The problem i see is that while i can find very affordable and good options they do not provide hardware raid or even if they do it is not the best hardware for freebsd. I prefer SW RAID, specifically ZFS, for two very large reasons: 1) Visibility: From the OS layer you have very good visibility into the health of the RAID set and the underlying drives. All of the lower end HW RAID solutions I have seen require proprietary software to manage the RAID configuration, usually from the physical system's BIOS layer. Finding good OS layer software to monitor the RAID and the drives has been very painful. If you don't know you have a failure, then you can't do anything about it and when you have a second failure you lose data. Running a HW RAID system and not being able to issue a simple command from the OS and see the status of the RAID scares me. 2) Error Detection and Correction: HW RAID relies on the drives to report read and write errors. With UNCORRECTABLE error rates of 10^-14 and 10^-15 and LARGE (1 TB plus) drives you are almost guaranteed to statistically run into UNCORRECTABLE errors over the life of a typical drive. ZFS has end to end checksums and can detect a single bad bit from a drive, if the set is redundant it can recreate the correct data and re-write it, effectively correcting the bad data on disk. NOTE: Larger, more expensive HW RAID systems address both of the above issues, but at a much higher cost in terms of money and management overhead. DISCLAIMER: I have been managing mission critical, cannot afford to lose it data under ZFS for over 5 years, with no loss of data (even with some horribly unreliable low cost HW RAID systems under the ZFS layer... if we had not used ZFS we would have lost data multiple times). -- Paul Kraus Deputy Technical Director, LoneStarCon 3 Sound Coordinator, Schenectady Light Opera Company ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

ZFS info WAS: new backup server file system options
On Dec 21, 2012, at 7:49 AM, yudi v wrote: I am building a new freebsd fileserver to use for backups, will be using 2 disk raid mirroring in a HP microserver n40l. I have gone through some of the documentation and would like to know what file systems to choose. According to the docs, ufs is suggested for the system partitions but someone on the freebsd irc channel suggested using zfs for the rootfs as well Are there any disadvantages of using zfs for the whole system rather than going with ufs for the system files and zfs for the user data? First a disclaimer, I have been working with Solaris since 1995 and managed lots of data under ZFS, I have only been working with FreeBSD for about the past 6 months. UFS is clearly very stable and solid, but to get redundancy you need to use a separate volume manager. ZFS is a completely different way of thinking about managing storage (not just a filesystem). I prefer ZFS for a number of reasons: 1) End to end data integrity through checksums. With the advent of 1 TB plus drives, the uncorrectable error rate (typically 10^-14 or 10^-15) means that over the life of any drive you *are* now likely to run into uncorrectable errors. This means that traditional volume managers (which rely on the drive reporting an bad reads and writes) cannot detect these errors and bad data will be returned to the application. 2) Simplicity of management. Since the volume management and filesystem layers have been combined, you don't have to manage each separately. 3) Flexibility of storage. Once you build a zpool, the filesystems that reside on it share the storage of the entire zpool. This means you don't have to decide how much space to commit to a given filesystem at creation. It also means that all the filesystems residing in that one zpool share the performance of all the drives in that zpool. 4) Specific to booting off of a ZFS, if you move drives around (as I tend to do in at least one of my lab systems) the bootloader can still find the root filesystem under ZFS as it refers to it by zfs device name, not physical drive device name. Yes, you can tell the bootloader where to find root if you move it, but zfs does that automatically. 5) Zero performance penalty snapshots. The only cost to snapshots is the space necessary to hold the data. I have managed systems with over 100,000 snapshots. I am running two production, one lab, and a bunch of VBox VMs all with ZFS. The only issue I have seen is one I have also seen under Solaris with ZFS. Certain kinds of hardware layer faults will cause the zfs management tools (the zpool and zfs commands) to hang waiting on a blocking I/O that will never return. The data continuos to be available, you just can't manage the zfs infrastructure until the device issues are cleared. For example, if you remove a USB drive that hosts a mounted ZFS, then any attempt to manage that ZFS device will hang (zpool export -f zpool name hangs until a reboot). Previously I had been running (at home) a fileserver under OpenSolaris using ZFS and it saved my data when I had multiple drive failures. At a certain client we had a 45 TB configuration built on top of 120 750GB drives. We had multiple redundancy and could survive a complete failure of 2 of the 5 disk enclosures (yes, we tested this in pre-production). There are a number of good writeups on how setup a FreeBSD system to boot off of ZFS, I like this one the best http://wiki.freebsd.org/RootOnZFS/GPTZFSBoot/9.0-RELEASE , but I do the zpool/zfs configuration slightly differently (based on some hard learned lessons on Solaris). I am writing up my configuration (and why I do it this way), but it is not ready yet. Make sure you look at all the information here: http://wiki.freebsd.org/ZFS , keeping in mind that lots of it was written before FreeBSD 9. I would NOT use ZFS, especially for booting, prior to release 9 of FreeBSD. Some of the reason for this is the bugs that were fixed in zpool version 28 (included in release 9). -- Paul Kraus Deputy Technical Director, LoneStarCon 3 Sound Coordinator, Schenectady Light Opera Company ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Can't get start_precmd to do *anything*
I'm working on an rc.d init script for a port, and I am clearly in need of
a clue.
I have a daemon that requires that a FIFO exist before it will start. The
FIFO is defined in the daemon's conf file. I could just point that out to
the user using warn, but I thought it would be nicer to simply take care
of it programmatically.
So I created this:
start_precmd=${name}_ck4fifo()
${name}_ch4fifo()
{
. ${pads_agent_conf}
echo Checking to see if ${PADS_FIFO} exists..
if [ ! -p ${PADS_FIFO} ]; then
echo ${PADS_FIFO} did not exist. Creating it now.
`/usr/bin/mkfifo ${PADS_FIFO}
else
echo ${PADS_FIFO} already exists.
fi
}
When I run the init script with rc_debug enabled, it calls the
start_precmd, but absolutely nothing happens. I don't even get the echos.
# /usr/local/etc/rc.d/pads_agent onestart
/usr/local/etc/rc.d/pads_agent: DEBUG: checkyesno: pads_agent_enable is set
to YES.
/usr/local/etc/rc.d/pads_agent: DEBUG: run_rc_command: start_precmd:

/usr/local/etc/sguil-sensor/pads_agent.conf
[root@buttercup4 /usr/ports/security/sguil-sensor-update/sguil-sensor]#
Error: Unable to read
/var/data/nsm/sguil-sensor/buttercup4.utdallas.edu/pads.fifo
I even tried this but got the same result.
${name}_ch4fifo()
{
warn You must create PADS_FIFO before starting ${name}.
warn Set PADS_FIFO in the ${pads_agent_conf} file.
}
The warn messages aren't in the messages file either, which is expected
behavior.
What the heck is going on here? Is something wrong with rc.subr on this
host? Am I missing something?

Is this a copy/paste error, or is your function actually called
_ck4fifo or _ch4fifo?
Both, but I fixed it and nothing changed.
${name}_ch4fifo()
I'm surprised sh isn't choking on this, you can't use ${name} in a
function name. Indirecting it is a waste of processing time, if I'm
honest; just use
start_precmd=pads_agent_prestart
pads_agent_prestart()
{

OK, I've done that. Still no change. {{{sigh}}}

Unexepected results when piping syslog to a fifo
I'm working on a project which requires that I pipe a remote syslog to a fifo so a daemon can parse the results. After some googling I *thought* that I had figured out how to configure syslog to do this. Here's the syslog.conf entry: + hostname.utdallas.edu *.* | cat /var/run/program/program.fifo This seems to work for one syslog message. The rest go to /var/log/messages. So I tried this: + hostname.utdallas.edu *.* | tail -f /var/run/program/program.fifo But that seems to do the same thing. I want these messages to be piped to the fifo *only* and not show up in local logs.

Observations:
1. When I first SSH into the box I see a long delay after the SSH
tunnel is setup before being prompted for a password, and I do not
know if this delay is related to the VBox issue. Details below.
Running the ssh server with more debugging will probably tell you what's
happening in this area.
Yup, I just have not had a chance to chase that one down, and
given that it happens once per SSH session, has not been a high
priority. I mentioned it in the spirit of full disclosure.
I would chock it up to network slowness, but I
do not see the same behavior with Firefox, xload, or xclock.
That's not a fair comparison, because tunneling a whole X server
involves passing a lot more events than tunneling an application to run
on your local server. This is particularly painful because the X
protocols are highly serial.
The VIrtualBox GUI (not the underlying VM console) should be
comparable to Firefox in terms of network load. Yes, xclock and xload
are much lower overhead as they are simpler apps. The difference
between Firefox (measured at under 10 seconds to open the window) and
VirtualBox (measured at 157 seconds to open the window) indicates that
_something_ is wrong.
Sorry if I was unclear. I am running 3 different VMs on this
server (soon to be more :-). One is WIn 2008 server as an RDP host for
a specific application, the others ar FreeBSD VMs, one for DNS and
DHCP, and the other for email / webmail. I manage the underlying Win
2008 instance via RDP (and that is how the end users connect), the two
FreeBSD VMs do not run a window manager at all and they are managed
via SSH connections. I use the VBoxHeadless executable to run the VMs
for production use. Normally I make config changes with the command
line tool VBoxManage, but in this case I had a FreeBSD VM that was not
booting so I needed the console (and to make various changes to the
config).
It is running the VBox management GUI on the physical layer server
that I am having fits with.
Is there any particular reason you don't let the X server run remotely
and attach to it with something more latency-friendly, like vnc? I would
expect that to work vastly better on any OS, just because you get X
(specifically, its tendency to head-of-line blocking) out of its own way.
The short answer to why X11 via SSH and not VNC for the management
is that I have not found a very clean way to have the VNC service
running for root without manual intervention to start it. Yes, I know
I could script it, but that adds one additional layer that needs to be
supported.
P.S. I did get my VM repaired, very slowly and painfully, but I still
need to track down the VBox GUI issue.

Re: eGalax USB touch panel on ExoPC Slate vs. FreeBSD and X11
I am pleased to see others having success at getting tablet input to work. I tried and failed with 8.x on my Fujitsu T-1010. Question: The button emulation. Did you add that or was it already there? I want to use Squeak Smalltalk on a tablet and the three button mouse emulation is a big deal, especially without a keyboard. The button emulation was already there. The BIOS on the ExoPC Slate uses it itself: when you power up the tablet, there are two areas you can press to enter the BIOS setup or the boot select menu. You can use the touch panel to set the BIOS options or choose the boot path and then tap the screen to select. The simulated button presses via screen taps are the only thing that work with the ums(4) driver out of the box. If you look at the HID collection dump from the mouse emulation mode, you can see it supports an X axis, Y axis and two button inputs. The touch screen synthesizes the button inputs internally based on tap patterns. Which leads me to my next question. What are you using for input? Is anyone working on handwriting recognition or does Apple still have the patents locked up? My goal is to be as much as possible like the Newton. Initially I was using a USB keyboard. The ExoPC Slate has two USB ports on the side. I have this old Targus USB I/O expander that also provides PS/2 keyboard and mouse inputs, along with RS-232 port, printer port and USB ethernet (Pegasus chipset, aue(4) driver). At minimum, USB keyboard is required in order to install FreeBSD. I also the USB thumbdrive installer to load the OS. After that I used the USB ethernet to load papckages. Once I had the OS installed, I switched to using a bluetooth keyboard. It's less clunky without the extra wires. Note that this was intended to be Intel's developer reference platform for the Meego OS (which is basically just another flavor of Linux). It came with Meego installed (it's now dual-booting Meego and FreeBSD). Meego includes an on-screen keyboard input widget which is something that plain X11 lacks. So for now, I need a physical keyboard. In addition to the eGalax touch screen, the Slate has: Atom N450 1.66Ghz CPU (can run i386 or amd64 versions of FreeBSD) 2GB RAM 64GB SSD storage Atheros 9285 WiFi Atheros bluetooth Intel Pineview graphics (1388x768 resolution) The bluetooth requires a binary blob firmware image to be loaded and I had to jigger the Intel xf86 video driver a little but it's all working now. -Bill On Fri, Nov 16, 2012 at 9:04 AM, Bill Paul wp...@freebsd.org wrote: Well... apparently I was able to get this to work on my own. To recap, I have an ExoPC Slate running FreeBSD 9.0 and xorg 1.7 with an eGalax USB HID touch screen. Out of the box, ums(4) claims it but doesn't like it. After investigating a bit more, I found that the screen has multiple HID collections associated with it: Collection type=Application page=Digitizer usage=Touch_Screen Collection type=Physical page=Digitizer usage=Finger Collection type=Application page=Generic_Desktop usage=Pointer Collection type=Physical page=Generic_Desktop usage=Pointer Collection type=Application page=Microsoft usage=0x0001 Collection type=Application page=Digitizer usage=Touch_Screen Collection type=Physical page=Digitizer usage=Stylus Collection type=Application page=Digitizer usage=Device_Configuration Collection type=Physical page=Digitizer usage=Finger The ums(4) driver is trying to use the 'Pointer' collection, but I think it may be getting confused by the X/Y ranges: Collection type=Application page=Generic_Desktop usage=Pointer Collection type=Physical page=Generic_Desktop usage=Pointer Input rid=1 size=1 count=1 page=Button usage=Button_1, logical range 0..1, physical range 1..2047 Input rid=1 size=1 count=1 page=Button usage=Button_2, logical range 0..1, physical range 1..2047 Input rid=1 size=16 count=1 page=Generic_Desktop usage=X, logical range 0..4095, physical range 0..4095 Input rid=1 size=16 count=1 page=Generic_Desktop usage=Y, logical range 0..4095, physical range 0..4095 End collection End collection There are two problems. First, the ranges are a little unusual. I think other mouse devices only have ranges from -127 to +127. Second, the input flags for the X and Y axis entries are 0x2 (HI_VARIABLE) and not HI_RELATIVE, which is what the usm(4) driver expects. This causes it to ignore the X and Y axis entries and only handle the button entries. I tried changing the code to accept just the HI_VARIABLE flag, but that still didn't make the cursor move. In any case, I was wrong that the problem is that the FreeBSD ums(4) driver doesn't handle gestures: it's just not flexible enough to handle this oddball pointer design. Anyway, go get it to work with X as a standard pointer device, I finally ended up doing the following: 1) Edited the uhid_probe() function in sys/dev/usb/input/uhid.c
Re: eGalax USB touch panel on ExoPC Slate vs. FreeBSD and X11
the 'Collection 2' line. For example, I plugged in a Dell USB mouse which was detected as /dev/uhid2, and modified the xorg.conf file to use it, and it worked fine. Long story short, the ums(4) driver just isn't smart enough to seamlessly handle the mouse emulation mode of the eGalax touch streen correctly. Maybe some day someone will fix it. I might take a look at it again if I can figure out how it works. -Bill -- = -Bill Paul(510) 749-2329 | Member of Technical Staff, wp...@windriver.com | Master of Unix-Fu - Wind River Systems = I put a dollar in a change machine.

eGalax USB touch panel on ExoPC Slate vs. FreeBSD and X11
Okay. I have my doubts that anyone will be able to answer this question but I'm going to try anyway. I have an ExoPC Slate tablet with FreeBSD 9.0 freshly installed on it, and it has the following touch screen device: ugen0.2: eGalax Inc. at usbus0 ums0: eGalax Inc. USB TouchController, class 0/0, rev 1.10/10.06, addr 2 on usbus0 tablet# usbconfig -u 0 -a 2 dump_device_desc ugen0.2: USB TouchController eGalax Inc. at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON bLength = 0x0012 bDescriptorType = 0x0001 bcdUSB = 0x0110 bDeviceClass = 0x bDeviceSubClass = 0x bDeviceProtocol = 0x bMaxPacketSize0 = 0x0040 idVendor = 0x0eef idProduct = 0x72a1 bcdDevice = 0x1006 iManufacturer = 0x0001 eGalax Inc. iProduct = 0x0002 USB TouchController iSerialNumber = 0x no string bNumConfigurations = 0x0001 I put the complete dmesg.boot from FreeBSD 9.0 on the tablet at: http://people.freebsd.org/~wpaul/exopc/dmesg.boot This device is detected by the ums(4) driver as a USB mouse. However, it doesn't quite work right as the ums(4) driver doesn't support multitouch gestures. It senses taps on the screen as button presses, but the cursor doesn't move. My question is: Can someone please tell me how to get this device to work with Xorg in FreeBSD (in this case, FreeBSD 9.0)? Here are some things I'd prefer you didn't tell me: - Try the uep(4) driver! Yes, I know about the uep(4) driver. It's for a different class of device. It doesn't support this one. - Try this patch! I'm hoping for an officially supported solution rather than an experimental patch. I mean, it's not that I don't appreciate someone's hard work and all, but these things have been around for a while now; you'd think support for it would already be integrated. And besides, it works with Linux. (You don't know how long I've been wanting to say that.) - Go to this web page! This _might_ be an acceptable answer _IF_ the said page contains specific instructions which are known to work. I already searched through many web pages before I came here. - Hey Bill, why don't you just write your own driver? Because I don't write FreeBSD drivers anymore, and I certainly don't write USB HID drivers, and because fuck you, that's why. (Note: I said that last part with a smile on my face, just in case it wasn't clear. Sometimes people have a hard time grasping my particular brand of humor.) This particular touch screen is basically a USB HID class device. I suspect there's some kind of gimmick you can do with libusb to get it to work with the X server, but I've already spent some time on various experimenmts and come up empty. As I said, I'm hoping there's official support for this kind of device, and I just need to know the right magic incantation to turn it on. Any help would be appreciated. -Bill -- = -Bill Paul(510) 749-2329 | Member of Technical Staff, wp...@windriver.com | Master of Unix-Fu - Wind River Systems = I put a dollar in a change machine.

If I add the parentheses, it doesn't find any files at all. This is FreeBSD 8.3 RELEASE. So how can I find these files without descending into directories I'm not interested in?

Re: How does freebsd supports ipx?
I suppose you should add options IPX line to your kernel
configuration file and rebuild/reinstall the kernel.
have a look at /usr/src/sys/conf/NOTES and/or
/usr/src/sys/{amd64,i386}/conf/NOTES for more information about kernel options

Hi Stuart,

The issue is that freebsd-update cannot update the ld-elf.so.1 binary
on a running system, so after the upgrade to 7.4 (or higher), the
system is not completely updated.
This message

Would it be easier to do an update by building from source? I've never used
freebsd-update myself so not had to troubleshoot these issues before.
That's probably the best way.
Bit I am wondering about this.
I upgraded several systems (physical and virtual machines) with
freebsd-update from 7.1 - 7.3 - 8.1 - 8.3 and also one system from 7.1 -
7.4 (with custom kernels) and did not encounter this. Did I just get lucky
then?
I couldn't comment on the freebsd-update(8) procedure as I've never used it.
But I'd personally upgrade the system by building from source. You can then
easily integrate your custom kernel and I would *imagine* you'd avoid the
issues you've encountered so far.
Make sure you read /usr/src/UPDATING thoroughly, and also check your customer
kernel options. Some changes have been made to more recent versions of FreeBSD,
such as the ata(4) driver. I believe in the past certain elements could be (and
still can be) added in a modular fasion, explicitly setting each element. Now,
you only need to have: device scbus, device ata and options ATA_CAM. Already
present in the GENERIC kernel config now. See man 4 ata for details. I hope
i've got that right, hopefully others will correct my comments if necessary but
in any case, reading the appropriate files will provide all the information
needed. For example: /usr/src/sys/conf/NOTES and
/usr/src/sys/{i386,amd64}/NOTES have more information about kernel options that
might be helpful and of interest to you.
