33.Sh NAME
34.Nm zpool-status

36.Sh SYNOPSIS
37.Nm zpool

44.
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.
59.Bl -tag -width Ds
60.It Fl -power
61Display vdev enclosure slot power status (on or off).
62.It Fl c Op Ar SCRIPT1 Ns Oo , Ns Ar SCRIPT2 Oc Ns …
63Run a script (or scripts) on each vdev and include the output as a new column
64in the
65.Nm zpool Cm status
66output.
67See the
68.Fl c
69option of
70.Nm zpool Cm iostat
71for complete details.
72.It Fl D
73Display a histogram of deduplication statistics, showing the allocated
74.Pq physically present on disk
75and referenced
76.Pq logically referenced in the pool
77block counts and sizes by reference count.
78.It Fl e
79Only show unhealthy vdevs (not-ONLINE or with errors).
80.It Fl g
81Display vdev GUIDs instead of the normal device names
82These GUIDs can be used in place of device names for the zpool
83detach/offline/remove/replace commands.
84.It Fl i
85Display vdev initialization status.
86.It Fl L
87Display real paths for vdevs resolving all symbolic links.
88This can be used to look up the current block device name regardless of the
89.Pa /dev/disk/
90path used to open it.
91.It Fl p
92Display numbers in parsable (exact) values.
93.It Fl P
94Display full paths for vdevs instead of only the last component of
95the path.
96This can be used in conjunction with the
97.Fl L
98flag.
99.It Fl s
100Display the number of leaf vdev slow I/O operations.
101This is the number of I/O operations that didn't complete in
102.Sy zio_slow_io_ms
103milliseconds
104.Pq Sy 30000 No by default .
105This does not necessarily mean the I/O operations failed to complete, just took
106an
107unreasonably long amount of time.
108This may indicate a problem with the underlying storage.
109.It Fl t
110Display vdev TRIM status.
111.It Fl T Sy u Ns | Ns Sy d
112Display a time stamp.
113Specify
114.Sy u
115for a printed representation of the internal representation of time.
116See
117.Xr time 1 .
118Specify
119.Sy d
120for standard date format.
121See
122.Xr date 1 .
123.It Fl v
124Displays verbose data error information, printing out a complete list of all
125data errors since the last complete pool scrub.
126If the head_errlog feature is enabled and files containing errors have been
127removed then the respective filenames will not be reported in subsequent runs
128of this command.
129.It Fl x
130Only display status for pools that are exhibiting errors or are otherwise
131unavailable.
132Warnings about pools not using the latest on-disk format will not be included.
