NAME
zpool-status — show detailed health status for ZFS storage pools
SYNOPSIS
zpool status [-DigLpPstvx] [-T u|d] [-c [SCRIPT1[,SCRIPT2]…]] [pool]… [interval [count]]
DESCRIPTION
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.
-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.
-i Display vdev initialization status.
-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.
-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.
-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.
-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(2). 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.
EXAMPLES
Example 1: Adding output columns
Additional columns can be added to the zpool status and zpool iostat output with -c.
