Hi,
I am having trouble with a 8 disk raidz2 pool. Last week I noticed any
commands that were accessing the pool's filesystems would hang (ls, df
etc...). The logs showed some read errors for two of the drives. I had
to power cycle the machine since I could not shut it down cleanly. After
rebooting, the machine would just hang when reading the ZFS config. I
was able to boot into maintenance mode using the 2009.06 live cd.
Running zpool import showed the pool as degraded but that it can be
imported:
pool: ZP02
id: 16281565776335757619
state: DEGRADED
status: The pool was last accessed by another system.
action: The pool can be imported despite missing or damaged devices.
The
fault tolerance of the pool may be compromised if imported.
see: http://www.sun.com/msg/ZFS-8000-EY
config:
ZP02 DEGRADED
raidz2 DEGRADED
c11t0d0 ONLINE
c11t1d0 ONLINE
c11t2d0 ONLINE
c11t3d0 UNAVAIL corrupted data
c11t4d0 ONLINE
c11t5d0 ONLINE
c11t6d0 ONLINE
c11t7d0 UNAVAIL corrupted data
(The pool was originally created in with SXDE 1/08).
I tried importing it with "zpool import -f ZP02". Initally, there are
some drive activity lights, but then it doesn't seem that anything is
happening. I let it sit for one week, but nothing ever completed.
Running "zdb -l" on the drives shows that the labels are intact for t0,
t1, t2, t5 and t6. t3, t4 and t7 show some "failed to read label"
errors.
Is there anything I can try to get this pool imported? Is the label
problem with c11t4 causing the issue (leaving me with three problem
disks)? I have ordred more memory for the machine in case it is needed
for the import to complete.
Thanks.
Peter.
