DESCRIPTIONlvs produces formatted output about logical volumes.
See lvm(8) for common options.
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 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.
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
Suppress the headings line that is normally the first line of
output. Useful if grepping the output.
Suppress the suffix on output sizes. Use with --units (except h
and H) if processing the output.
Comma-separated ordered list of columns. Precede the list with
'+' to append to the default selection of columns instead of
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_profile, lv_read_ahead, lv_size, lv_tags,
lv_time, lv_uuid, metadata_lv, mirror_log, modules, move_pv,
origin, origin_size, pool_lv, raid_max_recovery_rate,
raid_min_recovery_rate, raid_mismatch_count, raid_sync_action,
raid_write_behind, region_size, segtype, seg_count,
seg_pe_ranges, seg_size, seg_size_pe, seg_start, seg_start_pe,
seg_tags, snap_percent, stripes, stripe_size, sync_percent,
thin_count, transaction_id, writebehind, 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: (C)ache, (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 pool
m(e)tadata or pool metadata spare.
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 cur‐
rently locked against allocation changes, for example during
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.
9 Volume Health: (p)artial, (r)efresh needed, (m)ismatches
exist, (w)ritemostly. (p)artial signifies that one or more
of the Physical Volumes this Logical Volume uses is missing
from the system. (r)efresh signifies that one or more of the
Physical Volumes this RAID Logical Volume uses had suffered a
write error. The write error could be due to a temporary
failure of that Physical Volume or an indication that it is
failing. The device should be refreshed or replaced.
(m)ismatches signifies that the RAID logical volume has por‐
tions of the array that are not coherent. Inconsistencies
are detected by initiating a "check" on a RAID logical vol‐
ume. (The scrubbing operations, "check" and "repair", can be
performed on a RAID logical volume via the 'lvchange' com‐
mand.) (w)ritemostly signifies the devices in a RAID 1 logi‐
cal volume that have been marked write-mostly.
10 s(k)ip activation: this volume is flagged to be skipped dur‐
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.
Use default columns that emphasize segment information.
String to use to separate each column. Useful if grepping the
Produce output immediately without sorting or aligning the col‐
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.
When used with --nameprefixes, output values in the field=value
pairs are not quoted.
