Kernel Panic on Scrub- *ISSUE RESOLVED

Post by elfpltfn » Sat Sep 22, 2012 8:31 am

UPDATE 9/24/2012
Added ram to get above the 1Gb ram/Tb pool storage recommendation and have had not further issues.
After adding the new ram, I was able to see my old system would have run out of ram right around 60% of the scrub, which is when the crash occurred.
END UPDATE

I have a ~10Tb pool (macZFS pool) that imports just fine, but at 61% through the first scrub, I got a KP.

panic(cpu 2 caller 0xffffff7f813bf8d9): "/staging/zevo-community-edition/src/uts/common/fs/zfs/zio.c:474 ZFS assertion failed: *countp > 0 (0x0 > 0x0)"@/staging/zevo-community-edition/src/uts/darwin/os/printf.c:62

Anything else I can provide to help?
Thanks

Please: which processes – other than those relating to ZEVO – used the pool and/or the physical disk(s) at/around the time of the panic?

How much memory in the MacPro3,1?

Also, if you like, paste the content of the .panic file in its entirety. Its list of kernel extensions may provide clues, and so on.

(Hint: if pasting panic information within a reply, use the full editor and paste as code.)

-None that I know of, its shared over afp, but it panicked overnight when none of the client machines were up. Its excluded from spotlight and TM. The machine was sitting under the stairs scrubbing, thats all.

How much memory in the MacPro3,1?
-4 Gb (currently out to grab 16)

I would love to but I never get the panic log, I did take a picture of the panic screen-

Side note: from the photograph, I guess that the Mac was once configured to be a client of a kernel core dump server.

If you no longer use a kernel core dump server (a separate Mac) – and if you'd prefer kernel panic information to be logged at the affected Mac – you can simply reset the NVRAM/PRAM.

Are you sharing the disk with file sharing?
Is Spotlight enabled?

yes, its shared over AFP (10.6.8)
Spotlight is disabled on the pool. (learned that lesson back on macZFS)

Thanks.

I got the same panic shortly after booting with a new external zpool attached.
the only thing using the pool was spotlight (I think)
It took me two tries to get spotlight to exclude the pool because it panicked so fast.

Since then it has been stable although I have't stressed it yet.

The machine is a macpro running 10.6.8 with 16G memory

Resolution?

elfpltfn, please, what was the resolution? To no longer attempt AFP for the share?

Added ram to get above the 1Gb ram/Tb pool storage recommendation and have had not further issues.
After adding the new ram, I was able to see my old system would have run out of ram right around 60% of the scrub, which is when the crash occurred.

(no problem with AFP sharing, but I'm on 10.6.8 before apple tied it to HFS+)
