    .Sh NAME
    .Nm zpool-status
    .Nd show detailed health status for ZFS storage pools
    .Sh SYNOPSIS
    .Nm zpool

    .
    .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 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.
   .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.
