Hi,
I have been wrestling with ZFS issues since yesterday when one of my disks sort
of died. After much wrestling with "zpool replace" I managed to get the new
disk in and got the pool to resilver, but since then I have one error left that
I can't clear:
pool: data
state: ONLINE
status: One or more devices has experienced an error resulting in data
corruption. Applications may be affected.
action: Restore the file in question if possible. Otherwise restore the
entire pool from backup.
see: http://www.sun.com/msg/ZFS-8000-8A
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
data ONLINE 0 0 0
raidz ONLINE 0 0 0
c4d0s0 ONLINE 0 0 0
c4d1s0 ONLINE 0 0 0
c5d0s0 ONLINE 0 0 0
c5d1s0 ONLINE 0 0 0
errors: The following persistent errors have been detected:
DATASET OBJECT RANGE
mos 15 0-524288
I am trying to backup the pool, but when I tar some of the filesystems, the
kernel panics with the following message:

I am running nv_38 and I was wondering if this error was fixed in nv_60 or not.
I tried to search the forums for something, but couldn't find anything.
Thanks a lot in advance for your help.
Bertrand.
