DESCRIPTION
lvs produces formatted output about logical volumes.
OPTIONS
See lvm(8) for common options.
--aligned
Use with --separator to align the output columns.
--binary
Use binary values "0" or "1" instead of descriptive literal values for columns that
have exactly two valid values to report (not counting the "unknown" value which
denotes that the value could not be determined).
--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 current list of columns, '-' to remove
from the current list of columns or '#' to compact given columns. The -o option can
be repeated, providing several lists. These lists are evaluated from left to right.
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, 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 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, (X) unknown
6 device (o)pen, (X) unknown
7 Target type: (C)ache, (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 Volume Health: (p)artial, (r)efresh needed, (m)ismatches exist, (w)ritemostly,
(X) unknown. (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 portions of
the array that are not coherent. Inconsistencies are detected by initiating a
"check" on a RAID logical volume. (The scrubbing operations, "check" and
"repair", can be performed on a RAID logical volume via the 'lvchange' command.)
(w)ritemostly signifies the devices in a RAID 1 logical volume that have been
marked write-mostly.
10 s(k)ip activation: this volume is flagged to be skipped during activation.
-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.
-S, --select Selection
Display only rows that match Selection criteria. All rows are displayed with the
additional "selected" column (-o selected) showing 1 if the row matches the
Selection and 0 otherwise. The Selection criteria are defined by specifying column
names and their valid values (that can include reserved values) while making use of
supported comparison operators. See lvm(8) and -S, --select description for more
detailed information about constructing the Selection criteria. As a quick help and
to see full list of column names that can be used in Selection including the list
of reserved values and the set of supported selection operators, check the output
of lvs -S help command.
--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.
