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. Due to concurrent writes on a live system, it is possible for both scrubs and resilvers to progress beyond 100% completion. .Bl -tag -width Ds .It Fl c Ar script1 Ns Oo , Ns Ar script2 Ns ,… Oc 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 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. If repeated, (-DD), also shows statistics on how much of the DDT is resident in the ARC. .It Fl d Display the number of Direct I/O read/write checksum verify errors that have occurred on a top-level VDEV. See .Sx zfs_vdev_direct_write_verify in .Xr zfs 4 for details about the conditions that can cause Direct I/O write checksum verify failures to occur. Direct I/O reads checksum verify errors can also occur if the contents of the buffer are being manipulated after the I/O has been issued and is in flight. In the case of Direct I/O read checksum verify errors, the I/O will be reissued through the ARC. .It Fl e Only show unhealthy vdevs (not-ONLINE or with errors). .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 i Display vdev initialization status. .It Fl j , -json Oo Ns Fl -json-flat-vdevs Oc Oo Ns Fl -json-int Oc \ Oo Ns Fl -json-pool-key-guid Oc Display the status for ZFS pools in JSON format. Specify .Sy --json-flat-vdevs to display vdevs in flat hierarchy instead of nested vdev objects. Specify .Sy --json-int to display numbers in integer format instead of strings. Specify .Sy --json-pool-key-guid to set pool GUID as key for pool objects instead of pool names. .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 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 p Display numbers in parsable (exact) values. .It Fl -power Display vdev enclosure slot power status (on or off). .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 Sy d Ns | Ns Sy u Display a time stamp. Specify .Sy d for standard date format. See .Xr date 1 . Specify .Sy u for a printed representation of the internal representation of time. See .Xr time 1 . .It Fl t Display vdev TRIM status. .It Fl v|-vv Displays verbose data error information, printing out a complete list of all files containing data errors since the last complete pool scrub. Specified twice .Pq Sy -vv prints out the complete list of all corrupt records within each corrupt file. 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. .El . .Sh EXAMPLES .\" These are, respectively, examples 16 from zpool.8 .\" Make sure to update them bidirectionally .Ss Example 1 : No Adding output columns Additional columns can be added to the .Nm zpool Cm status No and Nm zpool Cm iostat No output with Fl c . .Bd -literal -compact -offset Ds .No #
