ZFS pool I/O failures
Type: |
Error |
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 zpoolprops(8) 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'.

scrub: none requested
config:
NAME STATE READ WRITE CKSUM
test FAULTED 0 13 0 insufficient replicas
sda9 FAULTED 0 7 0 experienced I/O failures
sdb9 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.
