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). In my experience, the amount of RAM depends on the amount of I/O not the amount of storage.

file corruption solution (soft-update or ZFS)
hello every body i have a question about fixing file corruption in freebsd. now i have freebsd8.2 and some times file corruption happened on it. this issue has a heavy cost for me and i want to avoid it or fixit it completely. so my question is: is it better to upgrade my freebsd to 9.1 and use soft update or migrate from UFS to ZFS? i heard so much about soft update -that is added in freebsd9.1- which can fix file corruption in acceptable way with low cost but i don't know how much is reliable and efficient. in the other hand, i think migration from UFS to ZFS can be another solution. as i read ZFS is is created to solve all the problems related integrity file system. is it reliable enough in comparison soft-update? now, i want to know which solution is better and why? thanks in advance s.motlagh ___ 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

If power failure is an issue, you have no guarantee of data loss protection unless you use networked storage to a safe place. UFS soft updates protects against file system corruption in case of power loss, no guarantees of individual file consistency. ZFS guarantees no silent failures, it doesn't guarantee protection, only that you'll know about it. There is no filesystem that can guarantee you won't lose data in a power failure. Hard drives are known to lie about what's been physically synced to disk out of cache in order to improve speed. If the power goes out at the wrong time, you can lose data.

Some MySQL clients will gratuitously change a connection attempt to localhost to use the /tmp/mysql.sock unix domain socket because it does perform a bit faster, and it seems they don't expect their users to just ask for a socket connection explicitly. You can test this fairly simply: set up your server with 'skip-networking' temporarily and try making client connections to it. Of course, for some language API's there's no option but to use a network socket -- Java being a case in point -- but that's the exception rather than the rule.

Solution: mysqld fails to run, can't create/find mysql.sock
Woke up to a screenful of error messages about failed mysql backups and found that for some reason, mysql was refusing to run at all. The issue was not just a missing mysql.sock but an inability to create one. I could do it by hand or at least create a file with the same name and permissions but it would be removed on the next attempt and then not replaced. Turns out the permissions on /tmp were not right. I didn't note them beforehand but setting them 1777 solved it. I would be interested in knowing how those permissions got changed. I rebooted the system early on in the process as I kept seeing messages like this: 120114 9:39:04 [ERROR] Can't start server : Bind on unix socket: Permission denied 120114 9:39:04 [ERROR] Do you already have another mysqld server running on socket: /tmp/mysql.sock ? Those are rubbish as error messages as they don't say the file can't be created or give any indication of the actual problem.

The message references a file that does not exist (but that mysql will cheerfully remove if found). There was no existing socket. Those two lines, taken together, tell me that a. mysql can't run without a socket and b. it thinks another process is running, bound to a socket that doesn't exist. Clear as mud. How about [ERROR] socket: /tmp/mysql.sock not found and/or [ERROR] socket:/tmp/mysql.sock could not be created perhaps with a helpful hint about permissions. If this was unusual, that would be one thing but I found quite a few references to the problem before I found the solution. Maybe it's a housekeeping thing but why would mysql need to destroy the file it uses for a socket and then recreate it when it could simply examine it and reuse it? Anyway, doesn't the mysql port want to keep the socket under /var/run/mysql/mysqld.sock or some such, to avoid issues with /tmp?

You can export your disks to the instances but with all things you gain some, you loose some. with the small machine (phenon 4, 8Gb), and vmware, the sistems is slow... and the MB does not accept more than 8GB. Besides I would need a version of each operating system for VMWARE.. and I do not know if vmware can be used for free. If even in a school you can, in other places you cannot, so I would cope with several platforms... Here I run a business based on FreeBSD, and the less different solutions the better... As someone else mentioned, consider netboot. The booted instance can do whatever they want to your hardware but disks are likely to have to be re-initialized each time, which is fine if you are using disks for swap and other temporary things. I use PXE because it is in the firmware of the MB... (almost always have)... some very old computers, does not boot anything but: floppy, cd, or HD... I choose CD.. one CD, boot all machines... Netboot is great too... With regard to VirtualBox, someone needs to fix it (probably just update the port). The network driver (IIRC) eats memory. Strange I have been using it in a day basis, and never had problems with that... the machine sometimes suffer power failure (3 months, or 1 month period).. I use FreeBSD 8.2 in zfs... with zmirror, and daylly snapshots... so I can go back anything till 5 days ago...

Many more recent (last 3 or 4 years?) motherboards have an option during POST to choose a boot device so you don't need to go into the BIOS setup screens. This system has the advantage that OS's are completely separate from each other. 2) Clonezilla. (Not very relevant aside... Back in the day of pentium 1's and 2 dual channel IDE controllers I solved this same problem with 3 hard disks, each set to be master, on a home made IDE cable with an extra connector so the three disks were plugged into the primary controller, and a 3 position rotary switch so only one disk would power up at a time. It took a bit of experimentation to find three disks that could coexist but it worked really well as long as one didn't switch over while the machine was on. I think I had FreeBSD, Windows and Netware).

I have had some success with multimedia/ffmpeg, at least this: ffmpeg -i file.mp3 -acodec copy -f rtp rtp://239.8.8.8:5000 -re does send a multicast stream which can be listened to with VLC (but not mplayer for some reason) on multiple hosts. Now I need to figure out how to stream live sound from /dev/dsp. All my attemps to record sound from a USB audio interface have resulted so far in a severely distorted growl instead of normal voice. Does anybody know how to figure out the sampling rate and other parameters of the sound card? cat /dev/sndstat does not output anything really useful. Why do you need multicasting anyway? To save bandwidth mostly, and it's fun to setup :).

For a full restore I boot into the new box on a liveusb os, partition/slice, newfs, mount and push the rsync back. All fairly easy and quick. With regard to database backups, we run all our mysql and oracle dbs on zfs. This allows us to put a global write lock on the db and flush everything to disk.

The more sensitive services I also backup using the protocol own duplication (master-slave database, DNS replication, etc.) With MySQL server replication, you can have the slave server running your actual database and ready to go in case the primary crashes. If the availability of the service is really critical, you must consider an high-availability solution, not only a backup.

echo Starting in `pwd`
for hoo in *; do
echo Found item $hoo
if [ -d $hoo ]; then
echo Pushing $hoo
cd $hoo
$0
cd ..
else
echo Processing file $hoo
fi
echo Going to next item
done
echo Finishing in `pwd`
# cd .. was here in original script
===
I shall be bold: this strikes me as a bug in bash. Am I off my nut here?
2) use find instead for the traversing of the file hierarchy
===
find $PWD -type f -execdir processingscript {} \;
===
I have tried both methods and on a small sample (10,000 files going only
3 deep) and there were no meaningful differences in execution time.

Re: SSO solution in ports?
Well, after a week of looking, I think I am going to go with a CAS solution, rubycas-server and rubycas-client. This supports several methods of authentication, including SQL, ActiveDirectory, LDAP, and GoogleAccounts. SQL is probably good enough for my application at the moment, but the LDAP option might come in handy someday. And it integrates nicely with Rails apps, which is my target platform. I looked at OpenID, which Rails also has good support for, but to my mind, it's just too complicated for the average user to use. I remember the first time I had to set one up, it was quite difficult to understand what it was they were looking for. I think it would scare away the average, non-technical, website user. Thanks for the ideas!

Re: installing ports xorg - Unknown solution
Heh, there were too many factors as possible culprits in the system. Glen Barber's command started to run, until I cancelled it when my laptop battery died... :D I'm not 100% sure what the problem was, but here's what I did... . The PC has a msk ethernet device, which I wasn't 100% sold I'd use it, . It's also behind a Linux-based firewall (corporate purchase) that ... doesn't always want to work, . I re-csup'd ports, it updated some stuff, but nothing in x11/ . I forgot it for the weekend, went into work, slapped it onto our other network (which isn't behind the Linux firewall), and initiated an install.. it started . Keeping it on the other network, I finished xorg, then installed kde4 with repeated fetch timeouts on both installs. . Remembered I had a broadcom ethernet card... installed it. . Finished installing everything, and is now my primary desktop at work. So, either the bad csup, odd msk ethernet, or the (VERY fustrating) Linux firewall was at fault.

CARP-Like Solution With Machines On Different Networks?
Hello All, I'm attempting to put a redundant fail-over system in place for a machine that I manage for a non-profit organization of modest budget. For the time being, I'm most interested in having MySQL and HTTP connections roll over to a backup system in the event that the primary machine goes down for some reason, and then return control to the primary box once it returns - nothing particularly fancy. After doing some research on the matter, it looks like CARP would be a winning solution - but only if the backup system was on the same network segment as the primary box. Given that there's no money to colocate a second backup system at the same facility as the main machine (and protection against failure at the colo facility is one of the primary drivers for the failover setup), however, it looks like CARP wouldn't be useful. That said, are there any solutions which behave similarly to CARP that I could use for a pair of machines connected solely via the Internet? For now, I'd even be happy if there was some way to simply do TCP port-level proxying, so to speak (i.e. connections come in to a given machine, and are proxied to the main system if it's up, but go to the backup box if not)? Thanks in advance for any advice you can provide.

If you can't or aren't willing to pay for a second machine, I doubt that any clustering solution is going to be workable for you, frankly. Most of the high-availability clusters I know about depend either on a multipath SAN or NAS setup to provide a common filestorage point for cluster members to synchronize with (the quorum drive for M$ clustered SQL server, similar for Sybase ASE cluster or Oracle Parallel Server [now Oracle RAC]), or require something like a hardware loadbalancer (Foundry ServerIron, NetScaler, etc) which acts to distribute transactions only onto the parts of the cluster which are up and working.

Thanks in advance for any advice you can provide. TCP level proxying is suitable for shared read-only distribution of traffic (ie, such as static web content going against a pool of webservers, all of which can serve any of the traffic coming their way). IPFW + natd can do this much via: -redirect_address localIP[,localIP[,...]] publicIP These forms of -redirect_port and -redirect_address are used to transparently offload network load on a single server and distribute the load across a pool of servers. This function is known as LSNAT (RFC 2391). For example, the argument tcp www1:http,www2:http,www3:http www:http means that incoming HTTP requests for host www will be trans- parently redirected to one of the www1, www2 or www3, where a host is selected simply on a round-robin basis, without regard to load on the net. ...but this paradigm simply won't work for content-aware traffic (ie, anything which has a per-user session) and it definitely won't work for a database. MySQL clustering is a less expensive possibility than most of the vendors listed above (M$ SQLServer EE is $25K per CPU, Oracle RAC is $60K per CPU), but even so Sun wants to bill at $2500 per day for a week of consulting to set it up for you.

Believe I have also see this happen with natd, Once Upon A Time natd needed to be restarted when the external IP address changed. Is possible for dhclient to do this automatically. As for a static IP address, many ISPs charge extra for this feature.

DHCP release/renew lease - elegant solution?
I have an always-on FreeBSD box which is connected to the internet. My ISP is some cable company and the IP address is determined via DHCP; I used to always get the same IP address but recently the address seems to be changing very frequently whenever I reboot the machine.

My goal is to do some dhclient magic which will automatically fix this problem without needing a reboot of the machine. If possible, I would like to have the same IP address as often as possible, but I'm not sure that this is possible. My FreeBSD version is 5.5, so it uses the ISC DHCP client, but the details between the current DHCP client and mine are probably insignificant. My /etc/dhclient.conf file is empty. I have been reading man pages, and it seems that the way to release, get a new IP address is this: dhclient -r dhclient fxp0 An except from my dhclient man page: The client normally doesn't release the current lease as it is not required by the DHCP protocol. Some cable ISPs require their clients to notify the server if they wish to release an assigned IP address. The -r flag explicitly releases the current lease, and once the lease has been released, the client exits. I could put this into a crontab and run it every 12 hours. However, this does not seem like a very elegant solution to my problem. I am wondering whether there is a more elegant solution.

It has to scan all the files to find new/changed files to backup. The r1soft agent monitors file system writes and backs up changed parts immediately. This does allow r1soft backup to restore the system to its latest state (10-15minutes ago state, thus continuous backup is achieved) as it continually updates the backups. Also has much less stress on the systems where the writes are not so much since it doesnt have to check every file at each backup cycle. Also r1soft cdp has support for MySQL where you can easily restore mysql data in table level if required. It is as well supported by a wide variety of web hosting automation systems for example H-Sphere ( http://www.parallels.com/hsphere/ ) etc. through plugins. Please see the info about continuous data protection: http://en.wikipedia.org/wiki/Continuous_Data_Protection Otherwise I am currently using BackupPC (which is pretty good in my opinion and easier to use compared to Bacula) to take nightly backups of the servers.

At the very least r1soft seems to be willing to communicate on this issue. First and foremost, the URL you gave is terse and out of context. Let people read the entire thread: http://forum.r1soft.com/showthread.php?p=3414 So let me throw around some ideas. First and foremost, David appears to be saying We'll take FreeBSD seriously if we can get proper documentation, and it needs to be thorough, that explains how to interface with devices on a block level so we can perform block-level backups and write our software appropriately. AFAIK we don't have any documentation that outlines that in a clear, concise manner. With regards to providing protocol documentation and letting the open-source community write the software, R1Soft is generally right. Time and resources are the biggest problem with open-source; do not think for a moment that just because millions of users can look at source code means they understand it, or even know how to write it, or will even *want* to. The majority do/will not. That said, I'd like to know exactly how low-level R1Soft's software truly is. dump(8), AFAIK, is block-level -- and that's a userland program. Does R1Soft's software *truly* require kernel-land? I have more to say on that issue (not against R1Soft, but speaking with regards to the current state of FreeBSD's developer count) if it truly does. I'm somewhat surprised that their software focuses on Linux and Windows and not Solaris and Linux, especially given that they're interested in dedicated server markets.

Re: continuous backup solution for freebsd?
First of all, I am not an r1soft advocate, but they seem to be making a software which is popular and affordable and interested in giving FreeBSD support... r1soft is not the issue here, the problem is that there is no way to do near continuous backups on FreeBSD servers. Jeremy Chadwick wrote: That said, I'd like to know exactly how low-level R1Soft's software truly is. dump(8), AFAIK, is block-level -- and that's a userland program. Does R1Soft's software *truly* require kernel-land? I have more to say on that issue (not against R1Soft, but speaking with regards to the current state of FreeBSD's developer count) if it truly does. I think you might not have understood the concept of near continuous backups. The R1Soft backup monitors the filesystem operations and backs up written blocks. So it has to know what is written and when to be able to back it up. The dump command simply reads/writes the blocks. It cant only read changed blocks. It has to read the whole thing (inefficient). Continuous backups as well as bare-metal-restore seem to be a key feature for many hosters. Regarding continuous backups: the GEOM gate class could be used for this. Meaning, I think it could be used as an alternate to R1Soft's software. The GEOM gate allows mirroring to a remote machine, am I not right? That would be more or less same as same as using RAID. The continuous backup (or near continuous) means that you can restore the filesystem to a point like 15 minutes ago, or 1 hour ago. Besides, I hear geom might have network delay problems and it is much more complicated setup to build two machines in mirror configuration just for backup purposes as well as you cant restore to a point in the past. Regarding bare-metal restoration I'm not aware of how to do that under FreeBSD, Linux, or even Solaris with ease. In most cases, companies develop their own PXE-booting environments which wipe the disks and reinstall + restore data as they see fit. There is no standard. OK. Actually there is more than one solution which can do bare-metal-restores for FreeBSD also. However those solutions at best rely on nightly backups of the filesystems. With R1Soft, you can restore the system to only few minutes before the total meltdown. Unrelated to bare metal restore, with normal backups you are not taking backups of files which are created/deleted often. For example this can be customer mails or if a hacker hacks the box and removes his trails. Even sometimes customers upload some file and remove from their computer the same they and then accidentally remove from the server. With R1Soft backup the data would go into the backup server right away and you an restore every single file independent of when it was put or removed. FreeBSD is loosing users because of this issue. Why does the number of FreeBSD users matter? Quantity does not necessarily represent quality. Thats a perfectly fine statement. But a quality product would be nothing without users. As well as this problem effects the quality. Consider a system which has sensitive data which shouldnt get lost, with continuous data protecton you can restore such failed system to only few minutes before the failure point. Doing this is currently impossible with FreeBSD. Best we can do is to return to previous snapshot taken (which might be a day old). This is an important design criteria since restoring the lost data might be time consuming and expensive. Thge issue is not even r1soft, they are just the most popular company giving such solution, only if there was at least one backup solution which could provide near continuous data protection... In addition to this, near continuous backups create less load on boxes with a lot of reads but little writes. Standart backups have to scan all the files to detect which files were changed. I'm sorry for sounding anti-FreeBSD, but the reality is that people should use whatever solutions work best for them -- if that's using Windows, Solaris, or Linux, great! Remember that open-source is about choice: and choice means supporting the possibility that someone chooses something else. Blind one-sided advocacy is very damaging to the open-source model and concept. I agree, and please dont shoot the messenger :) I just have a bunch of customers who would use FreeBSD but not using only because of this problem. In addition to that I myself would like to use near continuous backups as well. I was just trying to inform the FreeBSD community here so if somebody can have some time to divert to giving the right advices to r1soft then we all could benefit from it. It doesnt even have to be free even, with a reasonable price they can probably hire somebody to work for building the basics of this feature. So the real question is, is there anybody who is willing and have the experience to help on this issue? Thanks, Evren ___ freebsd

Re: continuous backup solution for freebsd?
of this. What's his background? I don't know, maybe some old guy who lives in a cave and has been studying BSD code in the steam tunnels; who knows. It's like they literally come out of the woodwork, while I don't see this sort of behaviour with Linux. With Linux, it's often Hi I work for large vendor, we're adding support for Linux, I need some help with regards to the following kernel piece... and they've got responses from 20 people in 24 hours. What I'm saying is that Linux has the upper hand here. More eyes, more people, more developers, larger community, larger vendor support, and much **much** faster turn-around time on fixes/bugs. We can sit here and argue about those facts all we want (it's the equivalent of doing burn-outs in an AMC Pacer in a parking lot -- wasted time, zero gain), but nothing changes the facts. Continuous backups as well as bare-metal-restore seem to be a key feature for many hosters. Regarding continuous backups: the GEOM gate class could be used for this. Meaning, I think it could be used as an alternate to R1Soft's software. The GEOM gate allows mirroring to a remote machine, am I not right? That would be more or less same as same as using RAID. The continuous backup (or near continuous) means that you can restore the filesystem to a point like 15 minutes ago, or 1 hour ago. What you're talking about sounds like filesystem snapshots, with an *immense* amount of granularity. Enterprise-level filers have this capability (I'm talking Network Appliance), and UFS2 with softupdates have it (called snapshots; but please be aware that there are *HUGE* problems with it, and it should not be relied upon for this kind of functionality) -- but nothing that can be restored within *minutes*. Even Netapp filers do not have that kind of granularity -- the amount of disk it would require would be astounding. Netapp filers often do snapshot generation hourly or nightly (it's configurable how often); minutes is unheard of. ZFS also has snapshot capability, but does not have real-time filesystem mirroring capabilities over a network (keyword: real-time). Besides, I hear geom might have network delay problems and it is much more complicated setup to build two machines in mirror configuration just for backup purposes as well as you cant restore to a point in the past. Well, GEOM gate is the only thing I know of which replicates filesystems over a network in real-time. Regarding bare-metal restoration I'm not aware of how to do that under FreeBSD, Linux, or even Solaris with ease.

I'm curious what sort of disk requirements are needed though (I guess it depends on how often changes happen on the filesystem). FreeBSD is loosing users because of this issue.

Re: continuous backup solution for freebsd?
Sorry for once more but: you can make incremental backups every x minutes with Bacula too .. it only takes one or two minutes on my box to scan for changed files for ~150GB (even faster if you tweak it a bit). It's not really a true continuous backup solution, but it's perfectly possible to restore directories/files for changes which occurred x minutes ago, and with retention periods of x days/months/years.

Although it takes more than 5 minutes to traverse millions of files using rsync independent of if they were changed or not (since rsync has to scan all the files to detect what is changed or not even if it only checks modification times, this takes time for so many files).

We can sit here and argue about those facts all we want (it's the equivalent of doing burn-outs in an AMC Pacer in a parking lot -- wasted time, zero gain), but nothing changes the facts. Sorry, I had to remove the whole bunch of text that you wrote :) but I get the point. I think it is a funny historical fact that BSD was commercially licensed way too long to allow Linux to be developed at first place. If BSD was not commercial at that times, Linus Torvalds probably wouldnt have started writing the Linux kernel. Thus we wouldnt be having this sort of conversation now and it might as well be that Microsoft wouldnt have become so huge. If we look at this from that point of view then eventually all BSD and Linux etc. are bound to disappear in time and Microsoft will stand all alone. But things can change one step at a time. I prefer(or try) to look at this positively. I thought it wouldnt hurt to ask for help if somebody could contact r1soft and perhaps ask a pile of money to develop a driver. It would have been a win-win situation eh? Right. We're definitely talking about snapshots, at least in concept. The fact that you're able to restore data within *minutes* is pretty impressive. I'm curious what sort of disk requirements are needed though (I guess it depends on how often changes happen on the filesystem). Well it is not so fine grained (5 to 10 minutes intervals as mentioned). http://www.r1soft.com/CDP.html (there is more information in the link above, with links to outside sources on the concept such as wikipedia articles etc.) I know some large hosters who use this technology with Linux servers. As a matter of fact the only reason they went with Linux instead of FreeBSD is because they cant get CDP with FreeBSD. I can ask how much space it is using and return back to you. But if you think about it for a second, a traditional backup program would copy the whole file even if there was 1 byte changed in it. Lets say 10mbyte file and 1 byte is changed. R1soft copies only 1 byte. Sure enough the tables can turn around if the filesystem was modified really a lot. But it looks like this type of solution is mostly effective (at least I didnt see anywhere that anybody is complaining that it is using too much disk space yet). The best is, all it would take for FreeBSD users to be able to utilize this technology is a driver to interface with r1soft agent and buy a license. Now I am not expecting anybody to write this for free or nobody is obligated to help. I just dont know anybody who can help so I thought I would drop in a line here so... I for one have never correlated snapshots and backup restorations (bare-metal recovery). I consider them completely separate things, and handled *very* differently. I have a feeling that no one's done this on FreeBSD because the amount of effort required is quite large. Someone did mention HAMMER on DragonflyBSD, but I have no knowledge of it or what it provides -- that said, Matt (Dillon)'s stuff is usually very, very good. I also dont know much about HAMMER either. But it doesnt look like it will make mainstream usage anytime soon on FreeBSD if it ever does. Actually I found a nice document here: http://www.dragonflybsd.org/hammer/hammer.pdf http://www.dragonflybsd.org/hammer/index.shtml It depends on how the filesystem is done. For example, with UFS2+SU snapshots, snapshot generation can take literally hours: completely unreasonable. While with ZFS, snapshot generation usually takes 2-3 seconds -- even on massive changes (e.g. take a snapshot, then rm a 600MB ISO image, then compare present vs. snapshot -- the diff is something like 40KBytes). Yes, but r1soft backup can restore a single file at a consistent state without restoring the whole filesystem from a graphical user interface and can restore mysql databases at a table level. While I agree that there might be different solutions that I dont know about, it just takes a driver to get this functionality on current FreeBSD systems without everybody to change to ZFS or HAMMER. One has to think, would people change their filesystems or install a driver? :) I would rather pay license fee to a backup program and use the driver. The price of the software is very well justified if I can return back to 5min before in my backups. The data I might loose is much more expensive. I'm sorry for sounding anti-FreeBSD, but the reality is that people should use whatever solutions work best for them -- if that's using Windows, Solaris, or Linux, great!
