ZFS-8000-HC - ZFS pool I/O failures
ZFS pool I/O failures
Type
- Error
- fault.fs.zfs.io_failure_wait
Severity
- Major
Description
- The ZFS pool has experienced currently unrecoverable I/O failures.
Automated Response
- No automated response will be taken.
Impact
- Read and write I/Os cannot be serviced.
Suggested Action for System Administrator
-
The pool has experienced I/O failures. Since the ZFS pool property 'failmode' is set to 'wait', all I/Os (reads and writes) are blocked. See the zpool(1M) manpage for more information on the 'failmode' property. Manual intervention is required for I/Os to be serviced. You can see which devices are affected by running 'zpool status -x':
# zpool status -x
pool: test
state: FAULTED
status: There are I/O failures.
action: Make sure the affected devices are connected, then run 'zpool clear'.
see: http://www.sun.com/msg/ZFS-8000-HC
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
test FAULTED 0 13 0 insufficient replicas
c0t0d0 FAULTED 0 7 0 experienced I/O failures
c0t1d0 ONLINE 0 0 0
errors: 1 data errors, use '-v' for a list
After you have made sure the affected devices are connected, run 'zpool clear' to allow I/O to the pool again:
# zpool clear test
If I/O failures continue to happen, then applications and commands for the pool may hang. At this point, a reboot may be necessary to allow I/O to the pool again.
Details
- The Message ID: ZFS-8000-HC indicates that the pool has experienced I/O failures. Take the documented action to resolve the problem.
