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.
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 default selection of columns instead
of replacing it.
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, (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)
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
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.
