DESCRIPTION
vgs produces formatted output about volume groups.
OPTIONS
See lvm for common options.
- --all
-
List all volume groups. Equivalent to not specifying any volume groups.
- --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.
-
Use -o vg_all to select all volume group columns.
-
Use -o help to view the full list of columns available.
-
Column names include: vg_fmt, vg_uuid, vg_name, vg_attr, vg_size, vg_free,
vg_sysid, vg_extent_size, vg_extent_count, vg_free_count, max_lv, max_pv,
pv_count, lv_count, snap_count, vg_seqno, vg_tags, vg_mda_count, vg_mda_free,
and vg_mda_size.
-
Any "vg_" prefixes are optional. Columns mentioned in either pvs (8)
or lvs (8) can also be chosen, but columns cannot be taken from both
at the same time.
-
The vg_attr bits are:
-
- 1
-
Permissions: (w)riteable, (r)ead-only
- 2
-
Resi(z)eable
- 3
-
E(x)ported
- 4
-
(p)artial: one or more physical volumes belonging to the volume group
are missing from the system
- 5
-
Allocation policy: (c)ontiguous, c(l)ing, (n)ormal, (a)nywhere, (i)nherited
- 6
-
(c)lustered
- -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.
