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

61 Run a script (or scripts) on each vdev and include the output as a new column
62 in the
63 .Nm zpool Cm status
64 output.
65 See the
66 .Fl c
67 option of
68 .Nm zpool Cm iostat
69 for complete details.
70 .It Fl i
71 Display vdev initialization status.
72 .It Fl g
73 Display vdev GUIDs instead of the normal device names
74 These GUIDs can be used in place of device names for the zpool
75 detach/offline/remove/replace commands.
76 .It Fl L
77 Display real paths for vdevs resolving all symbolic links.
78 This can be used to look up the current block device name regardless of the
79 .Pa /dev/disk/
80 path used to open it.
81 .It Fl p
82 Display numbers in parsable (exact) values.
83 .It Fl P
84 Display full paths for vdevs instead of only the last component of
85 the path.
86 This can be used in conjunction with the
87 .Fl L
88 flag.
89 .It Fl D
90 Display a histogram of deduplication statistics, showing the allocated
91 .Pq physically present on disk
92 and referenced
93 .Pq logically referenced in the pool
94 block counts and sizes by reference count.
95 .It Fl s
96 Display the number of leaf vdev slow I/O operations.
97 This is the number of I/O operations that didn't complete in
98 .Sy zio_slow_io_ms
99 milliseconds
100 .Pq Sy 30000 No by default .
101 This does not necessarily mean the I/O operations failed to complete, just took an
102 unreasonably long amount of time.
103 This may indicate a problem with the underlying storage.
104 .It Fl t
105 Display vdev TRIM status.
106 .It Fl T Sy u Ns | Ns Sy d
107 Display a time stamp.
108 Specify
109 .Sy u
110 for a printed representation of the internal representation of time.
111 See
112 .Xr time 2 .
113 Specify
114 .Sy d
115 for standard date format.
116 See
117 .Xr date 1 .
118 .It Fl v
119 Displays verbose data error information, printing out a complete list of all
120 data errors since the last complete pool scrub.
121 .It Fl x
122 Only display status for pools that are exhibiting errors or are otherwise
123 unavailable.
124 Warnings about pools not using the latest on-disk format will not be included.
