PCBSD: journaled soft-updates

Hello all.
Code: 
$uname -a                                       
FreeBSD pcbsd-1033 9.1-RELEASE FreeBSD 9.1-RELEASE #2: Tue Nov 27 03:06:52 UTC 2012     root@darkstar:/usr/obj/pcbsd-build90/fbsd-source/9.1/sys/GENERIC  i386
My PC start crash last day every 5-10 minutes. I have journaled soft-updates on PC ufs and after each abnormal reboot PC start very fast (fs was marked clean). I thought it was problem with RAM or motherboard, but when I fsck my fs in single user mode (not using journal) my PC stop crashes.

Ok, what the goal of using journaled soft-updates if it is not useful?

Sorry for my English.

An easy way to find out if SUJ is causing the problem would be to turn it off. Boot in single user mode, use tunefs(8) -j disable on each filesystem.

If it still crashes... that was not the problem. But it removes one item from the list of possible causes.

PC stop crashes when I done fsck on FS in single user mode. My question was about unstable of SUJ after abnormal reboot. No one see something like that?
 
Nope. It sounds more like you have hardware issues, perhaps some bad sectors on the disk.
 
When I first tried SUJ with 9.0, it was unstable and I disabled it. There have been updates since then, but it still prevents the use of dump(8) on those filesystems, so I don't use it.

What was unstable when you using SUJ?

I am planing to migrate from zfs to ufs+suj on servers with shared hosting...

Thanks.
 
It's been a while, but I recall reboots and overall instability. The same hardware with just softupdates is fine. And I have not tried SUJ lately, it may be better.

Not necessarily. Under the hood, PC-BSD is basically just a FreeBSD release. However, PC-BSD does have its own unique quirks and this forum is specifically for FreeBSD. So, questions about PC-BSD are usually tolerated here but please do understand that if you ask your question here the response will almost always have FreeBSD in mind and may not necessarily apply to PC-BSD. If at all possible, ask on the PC-BSD forums first. If they don't know the answer and the question is about the underlying system rather than the PC-BSD coating, it's okay to try here but be prepared to back-translate the answer from FreeBSD to PC-BSD yourself.
