PostPosted: Thu Jan 29, 2015 3:45 am    Post subject: ZFS kernel panic Reply with quote

I've tried to debug this a little, and have determined it's NOT the kernel itself.. I used to be running 3.12.21-gentoo-r1, and now I'm running 3.17.7-gentoo.. but during my upgrades I'm pretty sure I went from a .062 version of zfs to a .063 (yes.. Its' been out for a while.. but I was slow to update this system.

Here is my bug during backups at night... it doesn't always happen though...?????

It looks vaguely similar to:

https://github.com/zfsonlinux/zfs/issues/2709

where the developers ask if you could please try turning on the debug USE flags
for sys-kernel/spl and sys-fs/zfs-kmod, something like:
Code:
USE=debug emerge -av -1 sys-kernel/spl sys-fs/zfs-kmod

then it may crash with an assertion during the backup, in which case, maybe
providing the assertion stack trace(s) might give the zfs developers some hints.

If you don't want to bother with debugging the most stable kernel/zfs combination appears to be:

kernel 3.16
zfs 0.6.2

As other people I had weird non-fatal segfaults with 3.17 and 0.6.3-r3.

0.6.2 only supports kernel 3.14.

I have similar issue running either 0.6.3-r3 on kernel 3.17 as well as 0.6.3 on kernel 3.16.5


I added to this to issue 3019 https://github.com/zfsonlinux/zfs/issues/3019
