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
|
|
Displays the detailed health status for the given pools.
|
|
If no
|
|
.Ar pool
|
|
is specified, then the status of each pool in the system is displayed.
|
|
For more information on pool and device health, see the
|
|
.Sx Device Failure and Recovery
|
|
section of
|
|
.Xr zpoolconcepts 7 .
|
|
.Pp
|
|
If a scrub or resilver is in progress, this command reports the percentage done
|
|
and the estimated time to completion.
|
|
Both of these are only approximate, because the amount of data in the pool and
|
|
the other workloads on the system can change.
|
|
.Bl -tag -width Ds
|
|
.It Fl -power
|
|
Display vdev enclosure slot power status (on or off).
|
|
.It Fl c Op Ar SCRIPT1 Ns Oo , Ns Ar SCRIPT2 Oc Ns …
|
|
Run a script (or scripts) on each vdev and include the output as a new column
|
|
in the
|
|
.Nm zpool Cm status
|
|
output.
|
|
See the
|
|
.Fl c
|
|
option of
|
|
.Nm zpool Cm iostat
|
|
for complete details.
|
|
.It Fl i
|
|
Display vdev initialization status.
|
|
.It Fl g
|
|
Display vdev GUIDs instead of the normal device names
|
|
These GUIDs can be used in place of device names for the zpool
|
|
detach/offline/remove/replace commands.
|
|
.It Fl L
|
|
Display real paths for vdevs resolving all symbolic links.
|
|
This can be used to look up the current block device name regardless of the
|
|
.Pa /dev/disk/
|
|
path used to open it.
|
|
.It Fl p
|
|
Display numbers in parsable (exact) values.
|
|
.It Fl P
|
|
Display full paths for vdevs instead of only the last component of
|
|
the path.
|
|
This can be used in conjunction with the
|
|
.Fl L
|
|
flag.
|
|
.It Fl D
|
|
Display a histogram of deduplication statistics, showing the allocated
|
|
.Pq physically present on disk
|
|
and referenced
|
|
.Pq logically referenced in the pool
|
|
block counts and sizes by reference count.
|
|
.It Fl s
|
|
Display the number of leaf vdev slow I/O operations.
|
|
This is the number of I/O operations that didn't complete in
|
|
.Sy zio_slow_io_ms
|
|
milliseconds
|
|
.Pq Sy 30000 No by default .
|
|
This does not necessarily mean the I/O operations failed to complete, just took
|
|
an
|
|
unreasonably long amount of time.
|
|
This may indicate a problem with the underlying storage.
|
|
.It Fl t
|
|
Display vdev TRIM status.
|
|
.It Fl T Sy u Ns | Ns Sy d
|
|
Display a time stamp.
|
|
Specify
|
|
.Sy u
|
|
for a printed representation of the internal representation of time.
|
|
See
|
|
.Xr time 2 .
|
|
Specify
|
|
.Sy d
|
|
for standard date format.
|
|
See
|
|
.Xr date 1 .
|
|
.It Fl v
|
|
Displays verbose data error information, printing out a complete list of all
|
|
data errors since the last complete pool scrub.
|
|
If the head_errlog feature is enabled and files containing errors have been
|
|
removed then the respective filenames will not be reported in subsequent runs
|
|
of this command.
|
|
.It Fl x
|
|
Only display status for pools that are exhibiting errors or are otherwise
|
|
unavailable.
|
|
Warnings about pools not using the latest on-disk format will not be included.
