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
.Em Device Failure and Recovery
section of
.Xr zpoolconcepts 8.
.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.

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 IOs. This is the number of IOs that
didn't complete in \fBzio_slow_io_ms\fR milliseconds (default 30 seconds).
This does not necessarily mean the IOs 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.
.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.
