DESCRIPTION
lvs produces formatted output about logical volumes.
OPTIONS
See lvm(8) for common options.
--aligned
Use with --separator to align the output columns.
--all Include information in the output about internal Logical Volumes that are components of normally-
accessible Logical Volumes, such as mirrors, but which are not independently accessible (e.g. not
mountable). The names of such Logical Volumes are enclosed within square brackets in the output.
For example, after creating a mirror using lvcreate -m1 --mirrorlog disk , this option will reveal
three internal Logical Volumes, with suffixes mimage_0, mimage_1, and mlog.
--nameprefixes
Add an "LVM2_" prefix plus the field name to the output. Useful with --noheadings to produce a
list of field=value pairs that can be used to set environment variables (for example, in udev(7)
rules).
--noheadings
Suppress the headings line that is normally the first line of output. Useful if grepping the
output.
--nosuffix
Suppress the suffix on output sizes. Use with --units (except h and H) if processing the output.
-o, --options
Comma-separated ordered list of columns. Precede the list with '+' to append to the default
selection of columns instead of replacing it.
Use -o lv_all to select all logical volume columns, and -o seg_all to select all logical volume
segment columns.
Use -o help to view the full list of columns available.
Column names include: chunk_size, convert_lv, copy_percent, data_lv, devices, discards, lv_attr,
lv_host, lv_kernel_major, lv_kernel_minor, lv_kernel_read_ahead, lv_major, lv_minor, lv_name,
lv_path, lv_read_ahead, lv_size, lv_tags, lv_time, lv_uuid, metadata_lv, mirror_log, modules,
move_pv, origin, origin_size, pool_lv, region_size, segtype, seg_count, seg_pe_ranges, seg_size,
seg_start, seg_start_pe, seg_tags, snap_percent, stripes, stripe_size, thin_count, transaction_id,
zero.
With --segments, any "seg_" prefixes are optional; otherwise any "lv_" prefixes are optional.
Columns mentioned in vgs(8) can also be chosen.
The lv_attr bits are:
1 Volume type: (m)irrored, (M)irrored without initial sync, (o)rigin, (O)rigin with merging
snapshot, (r)aid, (R)aid without initial sync, (s)napshot, merging (S)napshot, (p)vmove,
(v)irtual, mirror or raid (i)mage, mirror or raid (I)mage out-of-sync, mirror (l)og device,
under (c)onversion, thin (V)olume, (t)hin pool, (T)hin pool data, raid or thin pool m(e)tadata
2 Permissions: (w)riteable, (r)ead-only, (R)ead-only activation of non-read-only volume
3 Allocation policy: (a)nywhere, (c)ontiguous, (i)nherited, c(l)ing, (n)ormal This is
capitalised if the volume is currently locked against allocation changes, for example during
pvmove(8).
4 fixed (m)inor
5 State: (a)ctive, (s)uspended, (I)nvalid snapshot, invalid (S)uspended snapshot, snapshot
(m)erge failed, suspended snapshot (M)erge failed, mapped (d)evice present without tables,
mapped device present with (i)nactive table
6 device (o)pen
7 Target type: (m)irror, (r)aid, (s)napshot, (t)hin, (u)nknown, (v)irtual. This groups logical
volumes related to the same kernel target together. So, for example, mirror images, mirror
logs as well as mirrors themselves appear as (m) if they use the original device-mapper mirror
kernel driver; whereas the raid equivalents using the md raid kernel driver all appear as (r).
Snapshots using the original device-mapper driver appear as (s); whereas snapshots of thin
volumes using the new thin provisioning driver appear as (t).
8 Newly-allocated data blocks are overwritten with blocks of (z)eroes before use.
9 (p)artial: One or more of the Physical Volumes this Logical Volume uses is missing from the
system.
-O, --sort
Comma-separated ordered list of columns to sort by. Replaces the default selection. Precede any
column with '-' for a reverse sort on that column.
--rows Output columns as rows.
--segments
Use default columns that emphasize segment information.
--separator Separator
String to use to separate each column. Useful if grepping the output.
--unbuffered
Produce output immediately without sorting or aligning the columns properly.
--units hHbBsSkKmMgGtTpPeE
All sizes are output in these units: (h)uman-readable, (b)ytes, (s)ectors, (k)ilobytes,
(m)egabytes, (g)igabytes, (t)erabytes, (p)etabytes, (e)xabytes. Capitalise to use multiples of
1000 (S.I.) instead of 1024. Can also specify custom units e.g. --units 3M
--unquoted
When used with --nameprefixes, output values in the field=value pairs are not quoted.
