Displays the detailed health status for the given pools. If no
pool is specified, then the status of each pool in the
system is displayed. For more information on pool and device health, see the
Device Failure and
Recovery section of
zpoolconcepts(7).
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.
--power
- Display vdev enclosure slot power status (on or off).
-c
[SCRIPT1[,SCRIPT2]…]
- Run a script (or scripts) on each vdev and include the output as a new
column in the
zpool
status
output. See the -c
option of
zpool
iostat
for complete
details.
-D
- Display a histogram of deduplication statistics, showing the allocated
(physically present on disk) and referenced (logically referenced in the
pool) block counts and sizes by reference count.
-e
- Only show unhealthy vdevs (not-ONLINE or with errors).
-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.
-i
- Display vdev initialization status.
-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
/dev/disk/ path used to open it.
-p
- Display numbers in parsable (exact) values.
-P
- Display full paths for vdevs instead of only the last component of the
path. This can be used in conjunction with the
-L
flag.
-s
- Display the number of leaf vdev slow I/O operations. This is the number of
I/O operations that didn't complete in
zio_slow_io_ms
milliseconds
(30000
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.
-t
- Display vdev TRIM status.
-T
u|d
- Display a time stamp. Specify u for a printed
representation of the internal representation of time. See
time(1).
Specify d for standard date format. See
date(1).
-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.
-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.
Additional columns can be added to the
zpool
status
and zpool
iostat
output with
-c
.
