DESCRIPTIONlvs produces formatted output about logical volumes.
OPTIONS
See lvm(8) for common options.
--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 creat‐
ing a mirror using 'lvcreate -m1 --mirrorlog disk', this option
will reveal three internal Logical Volumes, with suffixes mim‐
age_0, mimage_1, and mlog.
--aligned
Use with --separator to align the output columns.
--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: lv_uuid, lv_name, lv_path, lv_attr,
lv_major, lv_minor, lv_read_ahead, lv_kernel_major, lv_ker‐
nel_minor, lv_kernel_read_ahead, lv_size, seg_count, origin,
origin_size, snap_percent, copy_percent, move_pv, convert_lv,
lv_tags, mirror_log, thin_pool, modules, segtype, stripes,
stripesize, regionsize, chunksize, seg_start, seg_start_pe,
seg_size, seg_tags, seg_pe_ranges, devices.
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: (c)ontiguous, c(l)ing, (n)ormal,
(a)nywhere, (i)nherited This is capitalised if the volume is
currently locked against allocation changes, for example dur‐
ing 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, mir‐
ror 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.
--segments
Use default columns that emphasize segment information.
-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.
--separator Separator
String to use to separate each column. Useful if grepping the
output.
--unbuffered
Produce output immediately without sorting or aligning the col‐
umns 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.
