disappearing snapshots
I've been playing with snapshots (mksnap_ffs) recently. I've got a script which does a daily snapshot and keeps 7 days of history. Last night, the machine crashed and when it came back up, all the snapshots referred to the current view of the disk, i.e. I lost the 7-day history. I'm running 5.3-release. Has anyone seen this? Snapshots should persist beyond reboots, shouldn't they? (Yes, I am doing the mdconfig and remounting the snap.)

We're trying to get FreeBSD to perform reasonably well, in comparison to Linux, or even what we should expect to see. We're getting about half the performance we get from gentoo on the same application (mysql). [snip] Thanks in advance for anyone that has a clue on this, and has anyone figured out why FreeBSD is just so amazingly slow compared to Linux. Have you looked around for different compilers and/or different compiler options? I was just remembering how different code can be, depending on which gcc, for example, was used, and definitely which optimization. (i.e. Try gcc -v on both systems to see if they match; next see if all compiler options match when they are compiling like -march=pentiumpro.) Meanwhile, I have heard good things about compiler fill in the blank for whatever. Not too long ago, I remember hearing about people who preferred to use, say, an Intel compiler for certain things. It might be interesting to see if FreeBSD 4.11 is just as slow as 5.x. And try feeding the right compiler flags using /etc/make.conf or its equivalent. You should also think about whether the file systems are mounted using similar, or equally-performing systems. Rumour has it that Linux file systems performance is [flame bait mysteriously deleted]... Your benchmark may produce some interesting results, for example, depending on whether it thrashes a disk, or mainly hits memory. Do they perform the same on small sized (cached) lookups and then FreeBSD bogs down on disk throughput, for example? Last, but not least, I have heard some not-so-impressive things about MySQL 4.1 when compared to 4.0. Perhaps the things I heard were in reality specific to FreeBSD, and so by dropping back to 4.0 on a test server, you might see an unexpected performance boost? (Be sure and delete the tables between runs.) 4.0 is still in the ports tree, and I have heard of some who wished they never upgraded to 4.1. But going backwards is not pretty for a live database, so test both versions now.

In 5.x, you get process scope threads by default, but it turns out MySQL is tuned for system scope threads, and this is particularly visible in the supersmack benchmark, which competes many client processes against a few server threads. I'm not sure what the condition is of libthr on 5.x, but you could give it a spin. In 6.x, libthr has been largely rewritten and is a great deal faster. I think there's a compile-time option to make libpthread use system scope threads but the details ellude me. The Linuxthreads library may well provide a substantial improvement -- not as good for MySQL as the 6.x libthr, but perhaps much more appropriate than libpthread. - Locking model. Make sure that debug.mpsafenet is set to 1 (i.e., there aren't components in the kernel that force Giant over the network stack. Chances are there are none, but it's worth checking). - Twiddling hyper-threading, which helps or hurts differently in various configurations. - On a UP system, consider compiling a kernel without options SMP to reduce locking overhead. I've found the single largest remaining factor to be threading package -- over the past year or so I've about doubled MySQL performance on 5.x leading up to 5.3, largely through SMP locking work, but the remainder of the difference appears to be in the threading package.

Re: FreeBSD MySQL still WAY slower than Linux
I've been working with Steve on this project. We've been playing with various tuning
factors, including kernel changes, different stripe sizes on the RAID, my.cnf
tuning, libmap.conf, and although we can gain a bit here and there, we can't account for
the doubling of performance with Gentoo. Anyway, I've included the dmesg and kernel
config.
And /etc/make.conf ?
The Gentoo install was pretty vanilla-flavoured, as neither Steve or I had
installed Gentoo before, and both of us are pretty rusty on any form of Linux.
IIRC Gentoo on install detects the processor type and sets
for gcc the -march option. FreeBSD does not. Also Gentoo defaults
to -O3 (or -O2? I don't have it anymore to check...), so better
to par in that also.
Since Gentoo compiles practically everything in place,
these parameters might affect the results quite much.
At least I would check this ;-)
BTW, if you will make world and kernel with -march set, you
probably better patch it, or you might get a broken loader
(sorry for cutpaste, tabs might be broken):

Similar (with more -mno-smthng) patches are applied by obrien to HEAD,

Incidentally, this does not seem to be I/O-bound. The data is big enough to
stay in the table cache anyway.
I just noticed these particular tests were done on FreeBSD without HTT, whereas
the Gentoo test was. However, I can tell you that in earlier runs, the
difference between HTT and non-HTT on FreeBSD for this benchmark was negligible.

In 5.x, you get process scope threads by default, but it turns out MySQL is tuned for system scope threads, and this is particularly visible in the supersmack benchmark, which competes many client processes against a few server threads. I'm not sure what the condition is of libthr on 5.x, but you could give it a spin. In 6.x, libthr has been largely rewritten and is a great deal faster. I think there's a compile-time option to make libpthread use system scope threads but the details ellude me. The Linuxthreads library may well provide a substantial improvement -- not as good for MySQL as the 6.x libthr, but perhaps much more appropriate than libpthread. You can set the environment variable LIBPTHREAD_SYSTEM_SCOPE to force libpthread to use system scope. This is easier than rebuilding libpthread (with SYSTEM_SCOPE_ONLY defined) and allows you to use M:N for some applications and 1:1 for others. -- DE ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]

I have a VIA 6420 SATA150 controller, which also has raid, but is not supported by -stable. Here are the main differences, as I see them: atacontrol RAID: - Only for ATA; - Compatible with quite a few ATA RAID card BIOS metadata formats, hence you can create the RAID using the RAID controller's BIOS menu; - Supports only two-way mirroring (IIRC); - Supports spares. gmirror: - Works with any GEOM provider (ATA, SCSI, ggate, etc.); - Uses the last sector of each RAID component to store its own metadata; - Supports N-way mirroring; - Does not support spares (though gmirror activate/deactivate can be used to associate a component with a mirror somewhat akin to having a spare). I found array rebuilding to be troublesome on atacontrol RAID---so much so I abandoned it and used vinum and then gmirror instead for my RAID 1. (I have a bootable geom_mirror setup, now.) Mind you, that was in the pre-ATA mk.III days, and I hear the RAID support underwent a big revamp in the mk.III rewrite.

I just want to make sure that you didn't overlook the part of the handbook where it says that you have to enable it. It seems that's exactly what happened. Thanks for pointing it out. By the way, the option -k won't work on non-directories at all, see also the manpage of setfacl. Ok, then the handbook needs fixing because it says The -k flag will remove all of the currently defined ACLs from a file or file system, which would seem to imply that it works on files. Naturally I would have known better if I had read the man page, but I didn't. Are handbook bugs handled through send-pr like everything else?

This can be caused by two things: * A memory leak in FreeBSD * Incorrect tuning of your kernel memory parameters and causing the kernel to run out of memory.

Re: kernel panic
Sorry I can't really help. I get the same thing after setting up my
vonage VOIP adapter. I did a tcpdump on the interface and saw that I was
getting a lot of UDP traffic. I updated my box as of last night and now
I don't get a panic anymore but the box just locks up instead w/out
panicing. I'm using ipnat and ipf w/ basically no ipf rules and only a
generic map for my nat. I tried recompiling ipnat and added 1000 to the
number of states to keep and it didn't help one bit.
Any help would be appreciated. I don't think my file systems can take
many more of these power cycles. But I'll help any way I can. I haven't
really done any kernel tracing or anything like that but if someone can
point me to a what I need to do I'll do it.
