DESCRIPTION
lvs produces formatted output about logical volumes.
OPTIONS
See lvm for common options.
- --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_attr, lv_major, lv_minor, lv_read_ahead, lv_kernel_major,
lv_kernel_minor, lv_kernel_read_ahead, lv_size, seg_count, origin, origin_size,
snap_percent, copy_percent, move_pv, convert_lv, lv_tags, mirror_log, 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, (p)vmove,
(s)napshot, invalid (S)napshot, (v)irtual, mirror (i)mage, mirror (I)mage
out-of-sync, under (c)onversion
- 2
-
Permissions: (w)riteable, (r)ead-only
- 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 during pvmove (8).
- 4
-
fixed (m)inor
- 5
-
State: (a)ctive, (s)uspended, (I)nvalid snapshot, invalid (S)uspended snapshot,
mapped (d)evice present without tables, mapped device present with (i)nactive table
- 6
-
device (o)pen
- --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 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.
