ZFS-8000-JQ - ZFS pool I/O failures

ZFS pool I/O failures

Type

Error

  fault.fs.zfs.io_failure_continue

Severity

Major

Description

The ZFS pool has experienced currently unrecoverable I/O failures.

Automated Response

No automated response will be taken.

Impact

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 'continue', read I/Os will continue to be serviced, but write I/Os are blocked. See the zpool(1M) manpage for more information on the 'failmode' property. Manual intervention is required for write 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 write 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
