|
|
|
|
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 zpoolprops(8) 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: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-HC
|
|
scrub: none requested
|
|
config:
|
|
|
|

|

|
|

|
|
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.
|
|
