45.Sh DESCRIPTION
46Displays the detailed health status for the given pools.
47If no
48.Ar pool
49is specified, then the status of each pool in the system is displayed.
50For more information on pool and device health, see the
51.Sx Device Failure and Recovery
52section of
53.Xr zpoolconcepts 7 .
54.Pp
55If a scrub or resilver is in progress, this command reports the percentage done
56and the estimated time to completion.
57Both of these are only approximate, because the amount of data in the pool and
58the other workloads on the system can change.

61Run a script (or scripts) on each vdev and include the output as a new column
62in the
63.Nm zpool Cm status
64output.
65See the
66.Fl c
67option of
68.Nm zpool Cm iostat
69for complete details.
70.It Fl i
71Display vdev initialization status.
72.It Fl g
73Display vdev GUIDs instead of the normal device names
74These GUIDs can be used in place of device names for the zpool
75detach/offline/remove/replace commands.
76.It Fl L
77Display real paths for vdevs resolving all symbolic links.
78This can be used to look up the current block device name regardless of the
79.Pa /dev/disk/
80path used to open it.
81.It Fl p
82Display numbers in parsable (exact) values.
83.It Fl P
84Display full paths for vdevs instead of only the last component of
85the path.
86This can be used in conjunction with the
87.Fl L
88flag.
89.It Fl D
90Display a histogram of deduplication statistics, showing the allocated
91.Pq physically present on disk
92and referenced
93.Pq logically referenced in the pool
94block counts and sizes by reference count.
95.It Fl s
96Display the number of leaf VDEV slow IOs.
97This is the number of IOs that
98didn't complete in
99.Sy zio_slow_io_ms
100milliseconds (default 30 seconds).
101This does not necessarily mean the IOs failed to complete, just took an
102unreasonably long amount of time.
103This may indicate a problem with the underlying storage.
104.It Fl t
105Display vdev TRIM status.
106.It Fl T Sy u Ns | Ns Sy d
107Display a time stamp.
108Specify
109.Sy u
110for a printed representation of the internal representation of time.
111See
112.Xr time 2 .
113Specify
114.Sy d
115for standard date format.
116See
117.Xr date 1 .
118.It Fl v
119Displays verbose data error information, printing out a complete list of all
120data errors since the last complete pool scrub.
121.It Fl x
122Only display status for pools that are exhibiting errors or are otherwise
123unavailable.
124Warnings about pools not using the latest on-disk format will not be included.
