See lvm(8) for common options.
Use with --separator to align the output columns.
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.
-H , --history
Include historical logical volumes in the output. (This has
no effect unless logical volumes were removed while the
configuration setting metadata/record_lvs_history was
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).
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 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
Use -o lv_all to select all logical volume columns, and -oseg_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
4 fixed (m)inor
5 State: (a)ctive, (h)istorical, (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, thin-pool (c)heck needed, suspended thin-
pool (C)heck needed, (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, where there are currently three groups of
Common ones for all Logical Volumes: (p)artial, (X)
(p)artial signifies that one or more of the Physical
Volumes this Logical Volume uses is missing from the
system. (X) unknown signifies the status is unknown.
Related to RAID Logical Volumes: (r)efresh needed,
(m)ismatches exist, (w)ritemostly.
(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
Related to Thin pool Logical Volumes: (F)ailed, out of
(D)ata space, (M)etadata read only.
(F)ailed is set if thin pool encounters serious failures
and hence no further I/O is permitted at all. The out of
(D)ata space is set if thin pool has run out of data space.
(M)etadata read only signifies that thin pool encounters
certain types of failures but it's still possible to do
reads at least, but no metadata changes are allowed.
Related to Thin Logical Volumes: (F)ailed.
(F)ailed is set when related thin pool enters Failed state
and no further I/O is permitted at all.
10 s(k)ip activation: this volume is flagged to be skipped
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.
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
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.
