.Sh DESCRIPTION
|
|
Clears device errors in a pool.
|
|
If no arguments are specified, all device errors within the pool are cleared.
|
|
If one or more devices is specified, only those errors associated with the
|
|
specified device or devices are cleared.
|
|
.Pp
|
|
If the pool was suspended it will be brought back online provided the
|
|
devices can be accessed.
|
|
Pools with
|
|
.Sy multihost
|
|
enabled which have been suspended cannot be resumed when there is evidence
|
|
that the pool was imported by another host.
|
|
The same checks performed during an import will be applied before the clear
|
|
proceeds.
|
|
.Bl -tag -width Ds
|
|
.It Fl -power
|
|
Power on the devices's slot in the storage enclosure and wait for the device
|
|
to show up before attempting to clear errors.
|
|
This is done on all the devices specified.
|
|
Alternatively, you can set the
|
|
.Sy ZPOOL_AUTO_POWER_ON_SLOT
|
|
environment variable to always enable this behavior.
|
|
Note: This flag currently works on Linux only.
