Recently upgraded a system from b98 to b114. Also replaced two 400G
Seagate Barracudea 7200.8 SATA disks with two WD 750G RE3 SATA disks
from a 6-device raidz1 pool. Replacing the first 750G went ok. While
replacing the second 750G disk, I noticed CKSUM errors on the first
disk. Once the second disk was replaced, I halted the system, upgraded
to b114, and rebooted. Both b98 and b114 gave the errors:
WARNING: can't open objset for tww/opt/dists/cd-8.1
cannot iterate filesystems: I/O error
How do I recover from this?
# zpool status tww
pool: tww
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.
