Background:
Large ZFS pool built on a couple of Sun 3511 SATA arrays. RAID-5 is done in the
3511s. ZFS is non-redundant. We have been using this setup for a couple of
months now with no issues.
Problem:
Yesterday afternoon we started getting checksum errors. There have been no
hardware errors reported at either the Solaris level or the hardware level.
3511 logs are clean. Here is the zpool status:
tsmsun1 - /home/root >zpool status -xv
pool: z_tsmsun1_pool
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.

errors: The following persistent errors have been detected:
DATASET OBJECT RANGE
z_tsmsun1_pool/tsmsrv1_pool 2620 8464760832-8464891904
Looks like I have possibly a single file that is corrupted. My question is how
do I find the file. Is it as simple as doing a find command using "-inum
2620"?
TIA,
john
