They're embedded-style server systems at remote client sites, about 1200 of them. The splash module is just a visual nicety which is displayed during startup - at least providing some feedback as to what the system is doing. These are systems aimed at a non-tech audience, so those niceties count. The alternative to that was either standard kernel messages during boot, or a silent boot, both of which tend to confuse the crap out of non-tech end users. Yeah I agree. I originally downloaded your patch, I think it was for a 6.X system back then ~2008-09ish possibly even 7.X and twiddled with it for a bit playing around with all the funkiness of TheDraw and getting that good ole feeling of BBS days. But that's usually about as far as I go with things like that as you could probably tell from above ;) I was going through my archive file directory probably last month and came across the copy of the program which made me remember that patch, funny coincidence that it comes back up now ;) I must say though having to use a reproducible .bin file over trying to figure out all the complexities of making a proper gzip'd xpm,bmp,pcx file was NICE! My first attempt ever making a splash image bmp was a fail due to manual reading problems but needless to say it was a pain. TheDraw nearly painless but how long can we seriously hold on to that program and will there ever be anything to replace it ? ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org

I had a little script that would remove broken links. I used to do it like

So I had to change it to
if stat -L $link | awk '{print $3}' | grep l /dev/null;
then rm $link; fi
but it is a lot less elegant.
What is the proper accepted way to remove broken links?
Stephen
You might find sysutils/symlinks interesting. I have been using it a long
time and have not had to consider adjusting much in the way of shell
scripting to remove dirty links.
-c == change absolute/messy links to relative
-d == delete dangling links
-o == warn about links across file systems
-r == recurse into subdirs
-s == shorten lengthy links
-t == show what would be done by -c
-v == verbose (show all symlinks)
Quite interesting though how such a little tweak has caused a massive
expansion of your command line and required utils.
Good luck,

What we want to do is find and resolve as many bugs as possible. I completely agree with Martin here. If your running it then your willing to loose what you have if you have not taken precaution to save your data somewhere else. Even though with that said ZFS does a pretty fine job of ensuring that nothing happens to it, it is still best practice to have a copy somewhere other than IN THAT BOX ;) Another note too, I think I read that you mentioned using the L2ARC and slog device on the same disk You simply shouldn't do this it could be contributing to the real cause and there is absolutely no gain in either sanity or performance and you will end up bottle-necking your system. To help us fix these bugs, a way to reproduce the bug from a clean start (e.g. in virtualbox) would be great and speed up finding the cause for the problem. Your problem looks like some sort of deadlock. In your case, when you experiene the hang, try running procstat -k -k PID in another shell (console). That will give us valuable information. Martin, I agree with the above that it may be some sort of live or dead lock problem in this case. It would be awesome to know if some of the following sysctl(8)'s values are and how this reacts when set to the opposite of their current values. vfs.zfs.l2arc_noprefetch: vfs.zfs.dedup.prefetch: vfs.zfs.prefetch_disable The reason why I say this is on one of my personal systems that I toy with the box cannot make it very long with prefetch enabled on either v15 or v28 after some 'unknown' commit to world on stable/8. Now this may actually be just a contributing factor that makes it happen sooner than it normally would but probably also directly relates to the exact problem. I would love to see this go away as I had been using the L2ARC with prefetch enabled for a long time and now all of a sudden just plainly does not work correctly. I also have about 19 core.txt.NN files from when this started happening with various stack traces. If you would like these just let me know and Ill privately mail them to you.

Command used to import in FreeBSD was: zpool import -fF -R / pool which told me that zil was missing, and to use -m I booted openindiana (which is the only distribution I could ifnd with a live CD supporting zpool v28) Doing a zpool import actually made it show that the pool had successfully been repaired by the command above. It did think that the pool was in use (and it was, as I didn't do a zpool export). So I run zpool import -f pool in openindiana, and luckily, all my files were there. Not sure if anything was lost... in openindiana, I then ran zpool export and rebooted into FreeBSD. I ran zpool import there, and got the same original behaviour of a zpool import hanging, I can't sigbreak it nothing. Only left with the option of rebooting. Back into openindiana, tried to remove the log drive, but no luck. Always end up with the message: cannot remove log: no such device in pool Googling that error seems to be a common issue when trying to remove a ZIL but while that message is displayed, the log drive is actually removed. Not in my case.. So I tried something brave: In Open Indiana zpool export pool rebooted the PC, disconnected the SSD drive I had use and rebooted into openindiana ran zpool import -fF -R / pool (complained that log device was missing) and again zpool import -fF -m -R / pool zfs status showed that logs device being unavailable this time. ran zpool remove pool log hex_number_showing_in_place It showed the error cannot remove log: no such device in pool but zpool status showed that everything was allright zpool export pool , then reboot into FreeBSD zpool import this time didn't hang and successfully imported my pool. All data seems to be there. Summary: v28 is still buggy when it comes to removing the log device... And once something is screwed, zpool utility becomes hopeless as it hangs. So better have a OpenIndiana live CD to repair things :( But I won't be trying to remove the log device for a long time ! at least the data can be recovered when it happens.. Could it be that this is related to the v28 patch I used (http://people.freebsd.org/~mm/patches/zfs/v28/stable-8-zfsv28-20101223-nopython.patch.xz and should have stuck to the standard one). Before anything else can you: (in FreeBSD) 1) Set vfs.zfs.recover=1 at the loader prompt (OK set vfs.zfs.recover=1) 2) Boot into single user mode without opensolaris.ko and zfs.ko loaded 3) ( mount -w / ) to make sure you can remove and also write new zpool.cache as needed. 3) Remove /boot/zfs/zpool.cache 4) kldload both zfs and opensolaris i.e. ( kldload zfs ) should do the trick 5) verify that vfs.zfs.recover=1 is set then ( zpool import pool ) 6) Give it a little bit monitor activity using Ctrl+T to see activity. You should have your pool back to a working condition after this. The reason why oi_127 can't work with your pool is because it cannot see FreeBSD generic labels. The only way to work around this for oi_127 would be to either point it directly at the replacing device or to use actual slices or partitions for your slogs and other such devices. Use adaNsN or gpt or gptid for working with your pool if you plan on using other OS's for recovery effects.

Try that with a ( make includes ) in that same directory and if it works
then the advisory will have to be revised.
so it should be
make obj
make depend
make includes
make make install

As a follow-up, after applying both patches presented in this thread(FreeBSD
8.2-PRERELEASE #5: Thu Nov 25 19:14:00 CST 2010),
http://lists.freebsd.org/pipermail/freebsd-stable/2010-November/060298.html
top -m io now displays much more info and is generally consistent with
gstat in that IO spikes occer around the same time. However, gstat and top
-m io are still not displaying any stats for 90%+ of my hard drive
indicator light blinks. Since the issue effects gstat as well, it doesn't
seem like it could be related to ZFS. When the system is basically idling,
the only consistent IO related entries are these;
6 root 15 0 1 12 0 13 20.00%
{l2arc_feed_threa}
6 root 15 0 1 12 0 13 20.00%
{arc_reclaim_thre}
6 root 15 0 1 12 0 13 20.00% {zvol
zoot/usr/ho}
6 root 15 0 1 12 0 13 20.00%
{txg_thread_enter}
6 root 15 0 1 12 0 13 20.00%
{txg_thread_enter}
Entries like these occur like clockwork on 30 sec intervals. My theory here
is that since the ZVOL has UFS + SU, this is causing a sync?
What I'm trying to diagnose is a much more frequent hard drive access which
occurs on approximately 2 sec intervals. I timed this by pinging localhost
and comparing the response to the blinks. It's very consistent although not
completely so as once in awhile the blink occurs every second. If I listen
carefully I can hear increased drive activity during many of these intervals
so the indicator light seems to be working correctly.
If anyone has ideas or tests they'd like me to run, it would be appreciated.
Perhaps it's some external component?
E.g. hald is known to perform some disk/media checks every two seconds.
As well syslod will also cause sync to happen prematurely when something
goes to log.
syslog.conf(5):
***
To ensure that kernel messages are written to disk promptly,
syslog.conf calls fsync(2) after writing messages from the kernel.
Other messages are not synced explicitly. You may prefix a pathname
with the minus sign, ``-'', to forego syncing the specified file
after every kernel message. Note that you might lose information if
the system crashes immediately following a write attempt. Neverthe-
less, using the ``-'' option may improve performance, especially if
the kernel is logging many messages.
***
This is obviously the old way of ensuring logs are written to disk
before crash but now ZFS is handled differently. Check to see if adding
'-' to your syslog entries relieves that problem as ZFS will do the
right thing to ensure your data is written to disk.

I did upgrade the system to the latest stable: 8.1-STABLE FreeBSD 8.1-STABLE #0: Sun Oct 31 11:44:06 PDT 2010 After that I did zpool upgrade and zfs upgrade -r all the filesystems. Currently I am running zpool 15 and zfs 4. Everything went fine with the upgrade but unfortunately my problem still persists. There's no difference in this aspect. I still have mfid devices. I also tried chmod-ing as you suggested /dev/mfid devices but zfs/zpool didn't seem to care and imported the array regardless. So at this point since no one else seems to have any ideas and we seem to be stuck I am almost ready to declare defeat on this one. Although the pool is usable I couldn't bring it back to exactly the same state as it was before the disk replacements took place. Disappointing indeed, although not a complete show stopper. I still think that if there's a way to edit the cache file and change the devices that might do the trick.

There were a lot of ZFS-related MFCs since then. I'd suggest updating to the most recent -stable and try again. I've got another idea that may or may not work. Assuming that GPT labels disappear because zpool opens one of the /dev/mfid* devices, you can try to do chmod a-rw /dev/mfid* on them and then try importing the pool again. --Artem The problem seems to be that its just finding the actual disk before it finds the GPT labels. You should be able to export the pool and then re-import the pool after hiding the disks that it is finding via /etc/devfs.rules file. Try adding something like (WARNING: This will hide all devices mfi) adjust accordingly: add path 'mfi*' hide To your devfs ruleset before re-importing the pool and that should make ZFS go wondering around /dev enough to find the appropriate GPT label for the disk it is trying to locate. It would seem to me that using '-d' in this case would not be effective as ZFS would be looking for 'gpt/LABEL' within /dev/gpt/ if memory serves correctly, and obviously path /dev/gpt/gpt/ would not exist. Also even if it did find the correct gpt label then it would be assuming its at a /dev path and not /dev/gpt/* and would fall back to finding the mfi devices after the next boot again. -- jhell,v ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org

I don't recall the eventual outcome, but there was a long thread on stable or hackers on how to ensure proper alignment and (minimun) 4k-sized writes to make sure the disk doesn't have to do a read-modify-write cycle, so try and search the archives. Though this might play a small part in your write performance with the EARS drives, this issue has more to do with the stat() calls and the ACL involvement with ZFS. This was sort of solved in 8.1-STABLE and from 3 cases that I know about and 1 being my own... write/read speeds have doubled from what can be seen to an effect of 8.1-RELEASE. You may want to either upgrade to stable/8 or use one of the snapshots from here: ftp://ftp.freebsd.org/pub/FreeBSD/snapshots/201010/ Stefan, thank you for your response. I'll try to find the topic you pointed. ad4 and ad6 are single-slice disks (UFS2 with soft updates) ZFS configuration is following: zpool create Z ad8 zfs create Z/music zfs create Z/video All ZFS parameters are default. kern.maxvnodes = 100 To test my configuration I recursively copied from ad6 to ad8 two directories. The first one contains MP3 files (average size = 10MB). The second one contains AVI files (average size = 1GB). To compare performance I repeated above tests with ad8 using UFS2 with soft updates. 18GB of MP3 files required 10m35s to copy to UFS2 and 21m40s to copy to ZFS. 30GB of AVI files required 16m6s to copy to UFS2 and 1h2m39s to copy to ZFS. I used for tests FreeBSD 8.1R amd64. Amount of RAM on my machine is 6GB.

That looks reasonable
last says:
reboot ~ th 16 sen 14:04
reboot ~ th 16 sen 14:03
shutdown ~ th 16 sen 13:59
and it's pretty good syncs with logs but there's no anybody access to
physical console 'cos it's not even plugged in. That's for the first.
Next, I've got, I believe, pretty strong passwords, and also root
can't log in directly, but wheel user also is in operators so he also
can reboot or shutdown, but there's no any attempts or successful
logins. All potentialy dangerous services run under their own
unprerileged users, and so on. Crontabs also doesn't contain scripts,
I prefer periodic system, and there's no anyway anything that cause
reboot.
Thing that worries me it that there were multiple reboots and shutdown
that goes up by itself without anyone pressing a button. And in
messages log there's fsck segment that indicates to unnormal shutdown
or reboot. It looks like it started to shutting down but was in some
case interrupted and after powering up it few times reboots itself.
But commonly FreeBSD doesn't reboot by it's own will.
The same hardware worked over a half a year under 8.0 stables without
such a problem. I just would like to understand from where this
problem comes up.
This machine doesn't contain any critical info so I'll wait for a bit.
Also I'd like to notice that recently I've tuned hdd's spindown exept
system hdd by atacontrol port, powerd and CPU frequency lowering in
idle, maybe something of this could cause this problem? And where
could I check this out?
You might just want to go through your /etc/rc.d/*, crontabs,
/etc/periodic/* and /etc/rc* to check for any commands that call
shutdown(8) or reboot(8).
Not really malicious but a rogue user that was once a staffer can plant
a shutdown/reboot command in any one of the above matching files and
have it run by at(1). This really sounds like the case here.
1). Check the above files. egrep -nr (shutdown|reboot) on those.
2). Inspect the files for at(1) reboot(8) shutdown(8) or paths to
unintelligible binaries that have been setuid=0(u+s) owner=root.
3). Keep in mind a rogue staffer may have well cp(1) shutdown(8) to
another command or created a script containing shutdown(8) to another
command that matches another system command or has replaced one.
Thats just a few things to go on for now. Others may have more to add to it.

Are there no alternative ways to handle? Put network Giant code into bunch of #ifdef's, after all. The situation was: an announcement was made that in X months, all network drivers need to be made to run Giant-free so that FreeBSD can drop Giant from the neworking stack to move forward. Within that period, most of the drivers were updated. Repeated postings were made to the mailing list that the following drivers still have not been converted, and need to be updated or they will be dropped. They weren't; they were droppped. No. See my answer to vwe@ that there were no proper announcements. With them, for example, someone could get sponsored to update these drivers which were needed by those FreeBSD users who can't maintain code themselves. That's a last resort, more likely volunteers will come, but you get the idea. So while it could still work, it was slowing down progress. If it is not ideology, then what is it?.. The fact of the matter is, FreeBSD is a big project with a finite number of developers. We try to keep as much coverage of systems as we can, but a reality of any large software engineering project is that older features sometimes have to be dropped to make progress. From time to time such critical cases could possibly be handled by another ways, I've mentioned one possible above. The code still exists in the repository for any interested party to pick up and modernize. I hope that for this particular case alternative from ports will be enough. But policy is not tied to one particular case, alas. Would you please stop provoking a situation for which you are no more involved in other than running FreeBSD. Thank you.

This setup (which is pretty standard) is providing abysmal interactive performance on an eight-core machine whenever I try to do anything CPU-intensive (such as building a port). Basically, trying to build anything from ports rapidly renders everything else so non-interactive in the eyes of the scheduler that, for instance, switching between virtual desktops (I have six of them in reasonably frequent use) takes about a minute of painful waiting on redraws to complete. Are you sure this is about the scheduler or maybe bad X11 drivers? Not 100%, but mostly convinced; I've just started looking at this. It's my first stab at what might be going on. X11 performance is usually pretty snappy. There's no paging pressure at all. From my experience: 1. system with Athlon II X2 250 CPU and onboard AMD graphics - no issues with interaction between buildworld and GUI with all KDE4 effects enabled (OpenGL). 2. system with comparable Core2 Duo CPU and onboard Intel graphics (G33) - enabling OpenGL desktop effects in KDE4 leads to the consequences like what you describe. With all GUI bells and whistles disabled the system behaves quite like the AMD system. All desktop effects are disabled. The graphics are from an nVidia GeForce 8500 GT (G86) with the X.org driver. (It's not _just_ desktop behaviour that's affected, though: the box runs a number of small headless [interactive] server processes which also appear to get rapidly starved of CPU time.) The behaviour isn't visible with the 4bsd scheduler; stuff generally remains snappy and responsive. I'll keep poking around and see if I can get to the bottom of it. I think sysctl kern.sched.preempt_thresh is too low, default is only 64. I always tune it up to 200 on my desktop machine which is running gnome and other GUI applications, for a heavy GUI deskkop, I would tune it up to 224 to get better result.

deleting files from sup/cvsroot-all/ did not help

This won't work. You need to do: make DEBUG_FLAGS=-g3 -ggdb -O0
The important part is not using -D. make.conf variables aren't
exported into the compiler environment (I'm not phrasing this
eloquently because I don't know how to describe it). The rest of the
gcc arguments I provided are highly recommended (especially -O0,
otherwise you probably won't get access to any variable data).
I can confirm this works, by the way. Look closely at the cc line

cc -O2 -pipe -march=nocona -I.

Not being picky but just wanted to let you know that the flags specified
to DEBUG_FLAGS that you have listed above are perfectly fine but for
those without the knowledge of how this is done, the last flag specified
is usually the flag that wins.
So for DEBUG_FLAGS=-g3 -ggdb -O0 the -ggdb flag would be the debugging
type of ELF binary produced making the '-g3' flag just redundant.
Now in case you wanted the effect of '-g3' and '-ggdb' you can specify
'-ggdb3' instead.
As for the compile that was listed above it seems as if the flags were
reorganized in some way leading to '-g3' ultimately taking the cake.
Irregardless you will still end up with a binary that can be debugged by
gdb(1)/kgdb(1) either way.
Attached is a script that I use after buildworld installworld to rebuild
libthr and libc that is helpful for debugging that you may or may not
find useful.

I would like to move to being able to build a cheap san-like storage area for a DB, I don't know how well it would work but I'd like to try it anyway since things like HP MSA's are hugely expensive. I like these suggestions of filling a second box and connecting this to the 1st box using these expanders and port replicators. I don't really need as fast as I can get as this is not a high-use DB backend or many user file server. A few users here and there but nothing that worries me about the bottleneck caused by these replicators. This way is ALOT better then my system of trying to export iscsi disks or something like that. This way I can add create a second box then have a cable into an expander or replicator on the 1st box, a 3rd box could then be added to the expander/replicator at a later date. There is a limit on how far this could go realistically, but I like this way. I could go further by adding SSD's for the L2ARC and ZIL if I wanted to. I found zfsbuild.com to be a quite nice site/blog Thanks for the link: zfsbuild.com I'm going to check that out. Anyway... not that this is a great solution but if it is windows clients that are connecting to this that your worried about and would like to split off storage to separate machines etc... you can use DFS with Samba. Imagine building two more machines and having them be completely transparent to the clients that connect to the main server. Using a Samba DFS server would allow you to distribute out the file-systems to different shares on different machines without the client ever having to know that the actual location that the directory lays on is another machine and allows you to easily migrate new servers into the network without client ever seeing the change. Implement ISCSI, ZFS HAST into this mix and you have yourself one hell of a network.

Re: About zfs + nfs stability
On 08/31/2010 09:21, Giulio Ferro wrote:
1) Is it a good idea to upgrade this production system to the latest 8
stable (8.1 stable I believe)? Is it really stable?
For this question alone, I can verify that it is stable to upgrade to
the stable branch. Though on one hand it might be reasonable for you to
locally merge changes from the two points of CDDL into your source tree.
Example: (Tested here)
cd /usr/src
svn merge svn://svn.freebsd.org/base/stable/8/cddl cddl
svn merge svn://svn.freebsd.org/base/stable/8/sys/cddl sys/cddl
If you do not have any local changes to your source tree for those parts
of the branch then you should not have any problems or conflicts upon
merge this will bring your system up-to-date with ZFSv14 in stable/8.
Another route if you use CVS would be to checkout the source tree using
Subversion and diff it locally but you should still end up with the same
result.
There are a few patches that I can recommend but they are for stable/8
that has been patched with ZFSv15 that is due to be committed some time
in September - November. Patches and descriptions below. And attached is
a UMA patch for the VFS subsystem that helps a little with performance
but not near as much as the patches below.
http://people.freebsd.org/~mm/patches/zfs/v15/stable-8-v15.patch
http://people.freebsd.org/~mm/patches/zfs/zfs_metaslab.patch
http://people.freebsd.org/~mm/patches/zfs/zfs_abe_stat_rrwlock.patch
And for the better performance question by upgrading... that is a real
hard question to answer not knowing your hardware implementation. There
really has not been that much of a performance increase that I can
account for regarding stable/8 vs. releng/8.1, or at least not yet.
PS: I have done minimal testing for V4: /nfs either my understanding of
it or the way it is setup to work is somewhat confusing but this is only
with very little knowledge of NFSv4 so please only take this as opinion
but I would not upgrade a production system to use V4: /nfs quite yet
unless the need demands it.

When i try zfs set sharenfs=-ro -network xxx.xxx.xxx.0/24,-maproot=0 xxx.xxx.xxx.1 data/linux/root /var/log/messages shows network/host conflict and bad exports list line. The general problem seems to be that with each zfs set sharenfs command, the corresponding in /etc/zfs/exports gets overwritten. Is there a workaround for this besides ignoring sharenfs and using hand edited /etc/exports? Thanks for any help, Hi Heinrich, All the sharenfs property is actually doing and maybe not exactly in this order is modifying /etc/zfs/exports with the interpreted contents of the sharenfs property and using a syntax that the native mountd(8) understands or at least tries to in a very simple way. After this is all done, mountd(8) recieves a HUP signal to inform if to reread /etc/exports /etc/zfs/exports. So traditionally everything is happening the way it always has been except for the fact your now using the zfs(1M) Sun command with our own patch on top of that to make it look like its doing what you see in *Solaris or at least the interpreted version. Currently we do not have a/the share(1M) command implemented. My suggestion would be to write a script either in Python or Perl or maybe even in C to parse your own command line arguments and adjust /etc/exports or /etc/zfs/exports accordingly depending on the type of filesystem your arguments point to and then send signal HUP to mountd(8). This will at least be a little more under your control without having to modify sources and deal with conflicts later. I would recommend that you disable using the sharenfs property at all if you choose to go this route as you may start to find inconsistencies among your shares. The reference code where this is all happening is: cddl/compat/opensolaris/misc/fsshare.c Disable handling of the sharenfs property (ZFS_PROP_SHARENFS): cddl/contrib/opensolaris/lib/libzfs/common/libzfs_dataset.c Personally I would love to see our version of the sharenfs version translated into something that is local to FreeBSD only like the org.freebsd:swap local property that we use to enable swap on zvol's. My theorized version of this would look a little like the following. zfs set \ org.freebsd:nfs='r...@192.168.1.0/24,root=0; r...@192.168.2.1,root=514' org.freebsd:nfs4='V4: ..' Where options are separated by commas and shares to different hosts or networks are separated by semicolons. But if you don't want to go through all this then you could always designate /etc/zfs/exports as a permanent share for users that are allowed to write and administered by the sharenfs property. And use /etc/exports as your extraneous read-only shares. Just a thought. Anyway! enough said. Good luck on your mission.

Hi Alexander,
Attached is a fix for one problem and one slight overlook for

The first second change was probably just an oversight but none the

Change1:
${daily_scrub_zfs_default_threshold=30} is missng the ':'
which would ultimately reset the users supplied value in
periodic.conf to 30.
I will have a look at this.
Change2:
${_scrub_diff} -le ${_pool_threshold} would cause the scrub
to be run on the day after the threshold was met. So I changed '-le'
- '-lt' which causes it to be run on the 30th day instead of the
31st day.
This depends how you define threshold... I had number of days between
scrubs in my mind. Now it depends what I wrote in the man page, if it
tells what I had in mind (I don't remember, I have to look at it
myself, but I'm not a native english speaker, so I may have not wrote
it good enough).
I believe that people in this case would think that if they set the
threshold to 12 days that its going to run on the same day that the
threshold was expired and not the 13th. Usually when thresholds are met
the commands are fired that same instance and not a day later.
This is not set in stone, if the majority of people want something
else, I'm surely not in the way.
Also I just noticed another confusing message 'at least for me' that
said starting first scrubbing (after reboot) of pool 'exports'. I read
that like it is going to scrub the pool after the next reboot. I
actually had to open up the script to double check that was not the
case. The new attached patch changes the message to starting scrub of
pool 'pool' so there is no confusion of when the scrub is actually
going to happen.

[CFT] [sys/conf/newvers.sh] Cleanup and additions.
Hello Stablers Heads, Based on the parts of the script with the additions for tracking source using git(1) I set out to add support for mercurial hg(1) and ended up cleaning some of the script while making some of those additions. This works exactly as before but a little more correct and with the additions to be able to track kernel sources or whole source tree with a local revision system. Example output follows (uname -v) from my system being tracked locally with mercurial. FreeBSD 8.1-STABLE #0 r211092M 55:65408c40b051 Mon Aug 9 07:03:32 EDT 2010 jh...@ujump.dataix.net:/usr/obj/usr/src/sys/MITHOP Inspiration for making these changes came from mercurial, OpenSolaris and finally http://wiki.freebsd.org/LocalMercurial Following is a list of changes that I have made that I believe people that are involved with the source may find useful. 1 file changed, 55 insertions(+), 35 deletions(-) This allows a user: * That is using csup(1) or cvsup(1) to locally keep track of the whole source tree or just the kernel part of the tree using svn(1), hg(1) or git(1). * That is using svn(1) to checkout their source tree to use hg(1) or git(1) to keep track of the whole tree or the kernel part of the tree. http://svn.freebsd.org/base/ * That is using git(1) to checkout their source tree to use hg(1) to keep track of the whole tree or the kernel part of the tree. http://spoerlein.net/gitweb/ This checks for: * SCM roots in src/ or src/sys for .svn, .hg, .git and acts accordingly if they exist while prioritizing using an SCM root in src/ before it uses src/sys/ * Then looks for acceptable binaries for svn(1), hg(1) git(1) within the select paths /usr/local/bin then /usr/bin. The paths may change for svn(1) or git(1) maybe mercurial if it ever becomes part of world. Currently I have set these to only look in /usr/local/bin. Cleanups: * Instead of using variables that shared the same name as their counterpart binaries to hold a revision number use more descriptive names like svnrev gitrev hgrev for revisions. Use git svnversion hg variables for their respective binaries. * Adjust the paths that are checked for binaries to be of only /usr/local/bin and /usr/bin. /bin is highly unlikely to hold svn(1), git(1) or hg(1). * Test for a SCM root in the source tree locations before we look for binaries. If these don't exist there is no need to know where svn or git are. * For git(1) always set work-tree and git-dir so there is no possibility to end up with a -dirty git(1) revision. * Remove extraneous touch version since the previous if statement already creates the file if its not found. * Inline the test for version file.

Please, look at conf/146828. That script shouldn't blindly assume where user installs his packages[1]. [1] using non-default LOCALBASE is a convenient way to identify non-conforming ports And that would be to identify non-conforming ports using non-standard locations. Though the option is available to look in a non-standard location for binaries, IMHO it does not belong here and I don't find that right for building world. I also find this method a little hard to adjust for targeting specific locations, for example if the base system finally had a svnversion(1) installed and we prefered that over use of a local installed port. Currently I can just subtract that path from any one of the given SCM's configured to work with this patch without effecting the others. I have had another idea along the likes of this but just throwing an entry point hook in that checks for the existence of a user built or supplied file if you will so newvers.sh can keep doing what it has been doing for all these years without the interruption for small changes like the ones were talking about now.

A few parts can be simplified, too. I agree with this. I had just copied it over from what was already existing and excepted by the original committee and whoever reviewed it.

Maybe someone else has an idea what could have changed between 7 and 8 to break it, and again between 8 and CURRENT to magically fix it again. I tracked this down further. I couldn't easily downgrade my 8.1 installation to see when the problem was introduced because the zpool version used is 14. So I tried to figure out, when the problem was solved in CURRENT. I started with the first possible revision that can boot off my v14 pool (r201143, Dec 28, zfs v14 commit). With this revision, I was able to trigger the MCE. Then I took some later revision (rev206010, Apr 1, chosen randomly), and I couldn't reproduce the problem. I started narrowing the revisions down until I found out, that while on r202386 I'm still able to trigger the MCE, r202387 seems to solve the problem on CURRENT: http://svn.freebsd.org/viewvc/base?view=revisionrevision=202387 Since John Baldwin mentioned this problem could be timing related, it seems reasonable, that a clock-related change could be fix it. But this commit seems to have been MFC'd to 8-STABLE and 8.1 (at least as far as I can tell) along with some other changes to amd64 specific code. I thought that maybe these other changes that have been MFC'd could have reintroduced the problem later on, but so far I could not reproduce the problem with newer CURRENT revisions. So, I actually nailed this one done to a single commit on CURRENT, but still cannot tell what the actual difference is compared to 8-STABLE/8.1. Any ideas how to proceed? Adding to this I remembered some specific commits that caught my attention when they happened.

CMCI is a new local APIC interrupt that fires when a threshold of corrected machine check events is reached. CMCI also includes a count of events when reporting corrected errors in the bank's status register. Note that individual banks may or may not support CMCI. If they do, each bank includes its own threshold register that determines when the interrupt fires. Currently the code uses a very simple strategy where it doubles the threshold on each interrupt until it succeeds in throttling the interrupt to occur only once a minute (this interval can be tuned via sysctl). The threshold is also adjusted on each hourly poll which will lower the threshold once events stop occurring. r206183 | alc | 2010-04-05 12:11:42 -0400 (Mon, 05 Apr 2010) | 6 lines MFC r204907, r204913, r205402, r205573, r205573 Implement AMD's recommended workaround for Erratum 383 on Family 10h processors.

I will try a device which has never had a UFS file system and see if the ufsid device is created. Looks like the former is an issue with geom tasting and it would be nice to get it fixed, but it is not what is causing my problem. It is the latter issue that causes the problems with gnome-mount. The real issue for me is that /dev/ufs/LABEL is removed on a mount while /dev/msdosfs/LABEL remains. hald easily works around ufsid by ignoring it, but the /dev/FS/LABEL has to be acted upon differently depending on which filesystem is involved. Do you use those labels for anything ? if not, I worked around this while I used gnome for a period with devfs.rules(5) example follows. rc.conf(5) add devfs_system_ruleset=your_system [your_system=10] add path 'ufsid'hide add path 'msdosfs' hide add path 'ufs' hide add path 'iso9660' hide add path 'reiserfs' hide add path 'ntfs' hide add path 'ext2fs' hide add path 'gpt' hide And you can do the same for the actual devices that you use a label for, so mounting devices like daN can just be done from /dev/label/LABEL. add path 'da0' hide # Do this only after it is labeled. add path 'label/DA0LABEL' mode 0600 user jhell group jhell With a little toying of the above you should get the desired effect you want in gnome. I do find it frustrating having to resort to using only generic labels for situations like this and believe firmly that the generic label should take precedence over all labels except gpt ufsid and result in the other name-brand labels disappearing not causing this frustration to happen. Having the multiple layers of labels available IMO is cause for confusion. Final note before I stretch this out like the Armstrong figurine ;), there was a case where I was using the module instead of having GEOM_LABEL option built into the kernel, this being loaded after the machine was already booted caused some strange results with the labels that I know of on 7.2-STABLE. I don't know if this still exists but the result from that was multiple labels still being available under /dev while its counterpart label was mounted. That caused Gnome/hald to get pretty confused.

The idea was to keep as much as possible out of the kernel so that it wouldn't add additional complexity for people who don't use it (but it certainly wouldn't offend me any to find it in there :-) ). I think this would probably be best handled by the script that is creating the snapshots. Though this is a nice feature how well would it be received upstream and in what period of time would we have to wait while maintaining are down-level patches. I would propose looking at the creation time of the snapshots while in creation mode and parsing for a time that is older than a use configurable variable so the script can take proper action when destroying snapshots before it tries to create a new one and look at a value comprised of either the quota property or a attribute like the previous one stated. I strongly urge against creating a attribute that the script would look for due to the reason it would take more involvement with the script to be specific to FreeBSD where as now it should be OS independent. # This works good enough to compare with date(1) +%s zfs get -o name,value creation | grep @ # This works for seeing exactly how much a snapshot is using zfs get -o name,value used |grep @ Between the above two examples a threshold can be achieved at which older data can expire faster or slower depending on your settings and provide an upper tolerance for space usage. Of course this can be refined and there is a whole lot that is left to be scripted around the above commands.

Of course you do not need the zfsadm group to do this. You could just
use the wheel group which in turn gives any member of that group su(1)
access to the root user, so you commands would turn into...
pw groupmod wheel -m {username}
chmod u+s,o-rx /sbin/zpool
Because this binary is already installed group wheel there is no need to
chown it. And this is a little more implicit that you trust anyone with
access to the zpool command will also be having access to su(1)
Pick one, and Ill leave the how to keep these permissions through

If I'm misunderstanding what the OP wants, then I welcome correction. I
read the Op to want users to be able to run zpool scrub, so I took
that literally -- /sbin/zpool scrub pool and nothing more.
No you are not misunderstanding but I am also taking into account that the
admin said I've been messing around with permissions most notably I
thought that he has tried the access control methods that are administered
through the use of zfs allow which also might be a possibility if the
admin has world/base on a zfsroot. Second thought that came to mind while
leaving the possibility open to him was your standard Unix file perms.
While thinking about the scenario in a quick sense, If this is disk
activity that the admin wants to grant to a user in the form of scrub on a
pool then the admin already must trust whoever he is planning to give
these rights and has taken into account the possibility of misuse which
has lead him here asking for advice.
sudo offers the ability for the OP to provide root-level access to
defined users and ONLY the ability to run /sbin/zpool scrub {pool} and
nothing more (e.g. not /sbin/zpool remove or similar). It could also
be used to define certain users to scrub only certain pools.
I hope so at least that's what it was designed for. Yes very well noted
just leaving the possibility open to the admin to use something other than
a third party package in case it is his policy to not have something like
that installed. It happens.
Your first and second solutions allow any user added to _zfsadm and
group wheel, respectively, the ability to use /sbin/zpool. I hear
zpool destroy -f is a fun command to run while the system
administrator isn't looking. :-)
Good thing in most cases you can recover a destroyed pool or at least
that's the way it was designed the last time I accidentally did that (-D).
Backups are also a good thing in the case of a angry over driven highly
motivated administrator or staff.

Barry,
What branch and revision was this run on ?
I need the above information because the output above just does not match
up quite as it should and I want to investigate when, where why as I
believe something else is going on here that is not on the behalf of
arc_summary.pl.
Or if you could provide me personally with the full output of the script
from the downloads section just to be sure in an attachment that would
work as well.
Thanks.

Ill mark this up on my todo. Thanks for the feedback I should have
something committed back within the next couple days, possibly even tonight.
I never recalculated for this difference as that area of the code was
just a formatting fix.
But as Jeremy has pointed out, it would have to verify against
__FreeBSD_version but since I already pull in the sysctl MIB
kern.osreldate I should be able to compare to that and say 70 or
higher make the above correction.
As this is mainly ZFS v13 dependent now I don't feel to bad doing what I
have stated above.
Thanks again,

As stated in src.conf(5)

The src.conf file contains settings that will apply to every build
involving the FreeBSD source tree; see build(7).
The src.conf file uses the standard makefile syntax. However, src.conf
should not specify any dependencies to make(1). Instead, src.conf is to
set make(1) variables that control the aspects of how the system builds.

It would be almost to the same effect of doing this at the end of your
make.conf except it has already been done for you elsewhere.
.if ${.CURDIR:M/usr/src*}
.include /etc/src.conf

Is there any particular reason you are upgrading from a production

Just wondering, is this using the base nfsd/mountd, or is there some in-kernel nfs code strictly for zfs? I haven't found much info on the share* options in the manpage or wiki. ZFS on FreeBSD's sharenfs option does nothing more than manage data in a flat file (/etc/zfs/exports) and automatically send a SIGHUP to mountd's pid (based on reading the contents of the file _PATH_MOUNTDPID).

Don't ask me how/why that happened). Possibly these were bugs that existed during ZFS's transitional phase between 7.x and 8.x, but the unreliable nature of the situation left a bad taste in my mouth. The workaround: Using /etc/exports to reference the local ZFS filesystems I want exported, HUP mountd, done. Above oddities/quirks no longer happened. And there's an added bonus: all your exports are therefore kept in one single place: a text file that's existed since what, 1989 or so? Of course, the advantage is that with ZFS properties you can inherit options -- that might be useful to some, but not to me. There's also known quirks/issues with the parsing logic with sharenfs. This was discussed in December 2009. Could you give an example of passing options that would say, limit to a subnet and map root to root using the zfs sharenfs command? zfs create pool/fs zfs set sharenfs=-maproot=blah -network x.x.x.x -mask y.y.y.y pool/fs Right now I'm more or less avoiding NFS as much as possible, as the number of severe/major bug reports on RELENG_8 keep coming in, and that scares me greatly. There is also this: http://www.freebsd.org/cgi/query-pr.cgi?pr=17 Which I filed a while back that shows a bug in at least stable/7 that does not unshare/remove shared filesystems from /etc/zfs/exports. PJD has taken this PR and asked for a followup if this can be confirmed on a 8.X system as he believes it is fixed there. If someone of this thread is running a 8.X system would you please followup to this PR with YES/NO it exists or not, and it would be greatly appreciated. I believe this also has a part of sending HUP to mountd but I could not test that either on stable/7 or stable/8. -- jhell ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org

Hi Barry,
This is a very nice idea so please do not get me wrong when I say
that I would rather stay away from having to open config files and start
comparing results. I don't feel that this is in the place of the script to
do this type of action and can lead to confusion upon the users behalf.
sysctl(8) is by far better off getting the values from a running system
rather than parsing values obtained from a file that does not change the
system except for after a reboot upon which the values outlined in
loader.conf can be obtained from sysctl mibs.
The latest version of the script that I have uploaded has the sysctl mibs
spilled out at the bottom. These are mibs that I felt were relevent to the
tuning of ZFS and FreeBSD obtained from various sources and memory recall
so I might have missed a few so if you or anyone else has a mib to be
added please forward them to me in a email and I will be sure to add it.
Regards, and thanks for the feedback.

Yes, it should more or less duplicate the sysctl values, but it may
make it more obvious where the settings are coming from, or if the
user has bad or ignored settings
Major problems with the above code:
1) Opens /boot/loader.conf for rw access; should be read-only
2) Makes the assumption /boot/loader.conf exists
3) Does not close the fd
4) Excessively quotes variables for no justified reason
5) Makes some bad assumptions about the contents of the file (ex.
comments with the word zfs in them would match)
The code should really be something like what's below. This should
be much more manageable as well (@tunables that is), although I always
worry when using grep()...
Very nice!,
Ill keep this for reference later on. This might just come in handy at
some point.
But for the sake of arc_summary.pl I feel this is beyond the scope of what
its intended use is. See previous email in response to Barry.
Thanks Jeremy

Matt Yes, Thank you for pointing this out. I have fixed this and it will be added to the the same url as before in about 3 or so hours from the time of this email. This update will also add some stats for L2 ARC as well. Thanks again. -- jhell ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org
