45 .
46 .Sh DESCRIPTION
47 Displays the detailed health status for the given pools.
48 If no
49 .Ar pool
50 is specified, then the status of each pool in the system is displayed.
51 For more information on pool and device health, see the
52 .Sx Device Failure and Recovery
53 section of
54 .Xr zpoolconcepts 7 .
55 .Pp
56 If a scrub or resilver is in progress, this command reports the percentage done
57 and the estimated time to completion.
58 Both of these are only approximate, because the amount of data in the pool and
59 the other workloads on the system can change.
60 .Bl -tag -width Ds
61 .It Fl -power
62 Display vdev enclosure slot power status (on or off).
63 .It Fl c Op Ar SCRIPT1 Ns Oo , Ns Ar SCRIPT2 Oc Ns …
64 Run a script (or scripts) on each vdev and include the output as a new column
65 in the
66 .Nm zpool Cm status
67 output.
68 See the
69 .Fl c
70 option of
71 .Nm zpool Cm iostat
72 for complete details.
73 .It Fl j Op Ar --json-int, --json-flat-vdevs, --json-pool-key-guid
74 Display the status for ZFS pools in JSON format.
75 Specify
76 .Sy --json-int
77 to display numbers in integer format instead of strings.
78 Specify
79 .Sy --json-flat-vdevs
80 to display vdevs in flat hierarchy instead of nested vdev objects.
81 Specify
82 .Sy --json-pool-key-guid
83 to set pool GUID as key for pool objects instead of pool names.
84 .It Fl d
85 Display the number of Direct I/O write checksum verify errors that have occured
86 on a top-level VDEV.
87 See
88 .Sx zfs_vdev_direct_write_verify
89 in
90 .Xr zfs 4
91 for details about the conditions that can cause Direct I/O write checksum
92 verify failures to occur.
93 .It Fl D
94 Display a histogram of deduplication statistics, showing the allocated
95 .Pq physically present on disk
96 and referenced
97 .Pq logically referenced in the pool
98 block counts and sizes by reference count.
99 If repeated, (-DD), also shows statistics on how much of the DDT is resident
100 in the ARC.
101 .It Fl e
102 Only show unhealthy vdevs (not-ONLINE or with errors).
103 .It Fl g
104 Display vdev GUIDs instead of the normal device names
105 These GUIDs can be used in place of device names for the zpool
106 detach/offline/remove/replace commands.
107 .It Fl i
108 Display vdev initialization status.
109 .It Fl L
110 Display real paths for vdevs resolving all symbolic links.
111 This can be used to look up the current block device name regardless of the
112 .Pa /dev/disk/
113 path used to open it.
114 .It Fl p
115 Display numbers in parsable (exact) values.
116 .It Fl P
117 Display full paths for vdevs instead of only the last component of
118 the path.
119 This can be used in conjunction with the
120 .Fl L
121 flag.
122 .It Fl s
123 Display the number of leaf vdev slow I/O operations.
124 This is the number of I/O operations that didn't complete in
125 .Sy zio_slow_io_ms
126 milliseconds
127 .Pq Sy 30000 No by default .
128 This does not necessarily mean the I/O operations failed to complete, just took
129 an
130 unreasonably long amount of time.
131 This may indicate a problem with the underlying storage.
132 .It Fl t
133 Display vdev TRIM status.
134 .It Fl T Sy u Ns | Ns Sy d
135 Display a time stamp.
136 Specify
137 .Sy u
138 for a printed representation of the internal representation of time.
139 See
140 .Xr time 1 .
141 Specify
142 .Sy d
143 for standard date format.
144 See
145 .Xr date 1 .
146 .It Fl v
147 Displays verbose data error information, printing out a complete list of all
148 data errors since the last complete pool scrub.
149 If the head_errlog feature is enabled and files containing errors have been
150 removed then the respective filenames will not be reported in subsequent runs
151 of this command.
152 .It Fl x
153 Only display status for pools that are exhibiting errors or are otherwise
154 unavailable.
155 Warnings about pools not using the latest on-disk format will not be included.
