20 lvs produces formatted output about logical volumes.
21
23 See lvm(8) for common options.
24 --aligned
26 Use with --separator to align the output columns.
27 --binary
29 Use binary values "0" or "1" instead of descriptive literal val‐
30 ues for columns that have exactly two valid values to report
31 (not counting the "unknown" value which denotes that the value
32 could not be determined).
33 --all Include information in the output about internal Logical Volumes
35 that are components of normally-accessible Logical Volumes, such
36 as mirrors, but which are not independently accessible (e.g. not
37 mountable). The names of such Logical Volumes are enclosed
38 within square brackets in the output. For example, after creat‐
39 ing a mirror using lvcreate -m1 --mirrorlog disk , this option
40 will reveal three internal Logical Volumes, with suffixes mim‐
41 age_0, mimage_1, and mlog.
42 --nameprefixes
44 Add an "LVM2_" prefix plus the field name to the output. Useful
45 with --noheadings to produce a list of field=value pairs that
46 can be used to set environment variables (for example, in
47 udev(7) rules).
48 --noheadings
50 Suppress the headings line that is normally the first line of
51 output. Useful if grepping the output.
52 --nosuffix
54 Suppress the suffix on output sizes. Use with --units (except h
55 and H) if processing the output.
56 -o, --options
58 Comma-separated ordered list of columns.
59 Precede the list with '+' to append to the current list of col‐
61 umns, '-' to remove from the current list of columns or '#' to
62 compact given columns. The -o option can be repeated, providing
63 several lists. These lists are evaluated from left to right.
64 Use -o lv_all to select all logical volume columns, and -o
66 seg_all to select all logical volume segment columns.
67 Use -o help to view the full list of columns available.
69 Column names include: chunk_size, convert_lv, copy_percent,
71 data_lv, devices, discards, lv_attr, lv_host, lv_kernel_major,
72 lv_kernel_minor, lv_kernel_read_ahead, lv_major, lv_minor,
73 lv_name, lv_path, lv_profile, lv_read_ahead, lv_size, lv_tags,
74 lv_time, lv_uuid, metadata_lv, mirror_log, modules, move_pv,
75 origin, origin_size, pool_lv, raid_max_recovery_rate,
76 raid_min_recovery_rate, raid_mismatch_count, raid_sync_action,
77 raid_write_behind, region_size, segtype, seg_count,
78 seg_pe_ranges, seg_size, seg_size_pe, seg_start, seg_start_pe,
79 seg_tags, snap_percent, stripes, stripe_size, sync_percent,
80 thin_count, transaction_id, zero.
81 With --segments, any "seg_" prefixes are optional; otherwise any
83 "lv_" prefixes are optional. Columns mentioned in vgs(8) can
84 also be chosen.
85 The lv_attr bits are:
87 1 Volume type: (C)ache, (m)irrored, (M)irrored without initial
89 sync, (o)rigin, (O)rigin with merging snapshot, (r)aid,
90 (R)aid without initial sync, (s)napshot, merging (S)napshot,
91 (p)vmove, (v)irtual, mirror or raid (i)mage, mirror or raid
92 (I)mage out-of-sync, mirror (l)og device, under (c)onversion,
93 thin (V)olume, (t)hin pool, (T)hin pool data, raid or pool
94 m(e)tadata or pool metadata spare.
95 2 Permissions: (w)riteable, (r)ead-only, (R)ead-only activation
97 of non-read-only volume
98 3 Allocation policy: (a)nywhere, (c)ontiguous, (i)nherited,
100 c(l)ing, (n)ormal This is capitalised if the volume is cur‐
101 rently locked against allocation changes, for example during
102 pvmove(8).
103 4 fixed (m)inor
105 5 State: (a)ctive, (s)uspended, (I)nvalid snapshot, invalid
107 (S)uspended snapshot, snapshot (m)erge failed, suspended
108 snapshot (M)erge failed, mapped (d)evice present without
109 tables, mapped device present with (i)nactive table, thin-
110 pool (c)heck needed, suspended thin-pool (C)heck needed, (X)
111 unknown
112 6 device (o)pen, (X) unknown
114 7 Target type: (C)ache, (m)irror, (r)aid, (s)napshot, (t)hin,
116 (u)nknown, (v)irtual. This groups logical volumes related to
117 the same kernel target together. So, for example, mirror
118 images, mirror logs as well as mirrors themselves appear as
119 (m) if they use the original device-mapper mirror kernel
120 driver; whereas the raid equivalents using the md raid kernel
121 driver all appear as (r). Snapshots using the original
122 device-mapper driver appear as (s); whereas snapshots of thin
123 volumes using the new thin provisioning driver appear as (t).
124 8 Newly-allocated data blocks are overwritten with blocks of
126 (z)eroes before use.
127 9 Volume Health, where there are currently three groups of
129 attributes identified:
130 Common ones for all Logical Volumes: (p)artial, (X) unknown.
132 (p)artial signifies that one or more of the Physical Volumes
133 this Logical Volume uses is missing from the system. (X)
134 unknown signifies the status is unknown.
135 Related to RAID Logical Volumes: (r)efresh needed,
137 (m)ismatches exist, (w)ritemostly.
138 (r)efresh signifies that one or more of the Physical Volumes
139 this RAID Logical Volume uses had suffered a write error. The
140 write error could be due to a temporary failure of that Phys‐
141 ical Volume or an indication that it is failing. The device
142 should be refreshed or replaced. (m)ismatches signifies that
143 the RAID logical volume has portions of the array that are
144 not coherent. Inconsistencies are detected by initiating a
145 "check" on a RAID logical volume. (The scrubbing operations,
146 "check" and "repair", can be performed on a RAID logical vol‐
147 ume via the 'lvchange' command.) (w)ritemostly signifies the
148 devices in a RAID 1 logical volume that have been marked
149 write-mostly.
150 Related to Thin pool Logical Volumes: (F)ailed, out of (D)ata
152 space, (M)etadata read only.
153 (F)ailed is set if thin pool encounters serious failures and
154 hence no further I/O is permitted at all. The out of (D)ata
155 space is set if thin pool has run out of data space. (M)eta‐
156 data read only signifies that thin pool encounters certain
157 types of failures but it's still possible to do reads at
158 least, but no metadata changes are allowed.
159 Related to Thin Logical Volumes: (F)ailed.
161 (F)ailed is set when related thin pool enters Failed state
162 and no further I/O is permitted at all.
163 10 s(k)ip activation: this volume is flagged to be skipped dur‐
165 ing activation.
166 -O, --sort
168 Comma-separated ordered list of columns to sort by. Replaces
169 the default selection. Precede any column with '-' for a reverse
170 sort on that column.
171 --rows Output columns as rows.
173 -S, --select Selection
175 Display only rows that match Selection criteria. All rows are
176 displayed with the additional "selected" column (-o selected)
177 showing 1 if the row matches the Selection and 0 otherwise. The
178 Selection criteria are defined by specifying column names and
179 their valid values (that can include reserved values) while mak‐
180 ing use of supported comparison operators. See lvm(8) and -S,
181 --select description for more detailed information about con‐
182 structing the Selection criteria. As a quick help and to see
183 full list of column names that can be used in Selection includ‐
184 ing the list of reserved values and the set of supported selec‐
185 tion operators, check the output of lvs -S help command.
186 --segments
188 Use default columns that emphasize segment information.
189 --separator Separator
191 String to use to separate each column. Useful if grepping the
192 output.
193 --unbuffered
195 Produce output immediately without sorting or aligning the col‐
196 umns properly.
197 --units hHbBsSkKmMgGtTpPeE
199 All sizes are output in these units: (h)uman-readable, (b)ytes,
200 (s)ectors, (k)ilobytes, (m)egabytes, (g)igabytes, (t)erabytes,
201 (p)etabytes, (e)xabytes. Capitalise to use multiples of 1000
202 (S.I.) instead of 1024. Can also specify custom units e.g.
203 --units 3M
204 --unquoted
206 When used with --nameprefixes, output values in the field=value
207 pairs are not quoted.
