zfs discuss - Jul 2010 - Random system hang build 134

Symptoms:

1. System remains pingable
2. When trying to ssh in terminal hangs after entering pass
3. At the console terminal hangs after entering pass
4. Problem persists after disabling snapshots/compression/dedup

Solution:

Hard reboot (A+F1 does not work)

Configuration:

Supermicro Mobo
24 x 2TB WD Black Drives (2 x 12 drive in RAIDZ2)
Mirrored OCZ 32GB SSD drives for OS (ZFS mirrored rpool)
Mirrored Intel extreme 64GB drives (ZIL)
Quad Port Intel Gb NIC - aggr1
12GB DDR3


Does anyone have any idea what the problem could be or how I can track this
down? Just so that you know I have 2 of these system with identical setup and
hardware so I have excluded the possibility that this could be a bad piece of
hardware.

I''ve seen similar issues.  However, it appears most of my problems stem
from ZFS.  I''d do something ZFS doesn''t like and then
I''d have to power cycle the server to get it back.  I actually wrote a
large post about my experiences with b134 and ZFS:

opensolaris.org/jive/thread.jspa?messageID=493644&tstart=0

I posted it in the opensolaris forum because it thought of it more as a b134
thing.

All I can say is that I hope you have your data backed up, and if you
don''t you might want to do that.
