SYNOPSIS
vgs [--aligned] [-d|--debug] [-h|-?|--help] [--ignorelockingfailure] [--nameprefixes] [--noheadings] [--nosuffix] [-o|--options [+]Field[,Field]] [-O|--sort [+|-]Key1[,[+|-]Key2[,...]]] [-P|--partial] [--rows] [--separator Separator] [--unbuffered] [--units hsbkmgtHKMGT] [--unquoted] [-v|--verbose] [--version] [VolumeGroupName [VolumeGroupName...]]
DESCRIPTION
vgs produces formatted output about volume groups.
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. Column names are: 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. Use -o help to view the full list of fields available.

The vg_attr bits are:

Permissions: (w)riteable, (r)ead-only

Resi(z)eable

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 hsbkmgtHKMGT
-
All sizes are output in these units: (h)uman-readable, (s)ectors, (b)ytes, (k)ilobytes, (m)egabytes, (g)igabytes, (t)erabytes. Capitalise to use multiples of 1000 (S.I.) instead of 1024. Can also specify custom (u)nits e.g. --units 3M
-
--unquoted
-
When used with --nameprefixes, output values in the field=value pairs are not quoted.
