Add `zpool` flags to control the slot power to drives. This assumes
your SAS or NVMe enclosure supports slot power control via sysfs.
The new `--power` flag is added to `zpool offline|online|clear`:
zpool offline --power <pool> <device> Turn off device slot power
zpool online --power <pool> <device> Turn on device slot power
zpool clear --power <pool> [device] Turn on device slot power
If the ZPOOL_AUTO_POWER_ON_SLOT env var is set, then the '--power'
option is automatically implied for `zpool online` and `zpool clear`
and does not need to be passed.
zpool status also gets a --power option to print the slot power status.

.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.
|
|
While the pool was suspended, it may have been imported on
|
|
another host, and resuming I/O could result in pool damage.
|
|
.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.
