vgs [-a|--all] [--aligned] [-d|--debug] [-h|-?|--help] [--ignorelockingfailure] [--nameprefixes] [--noheadings] [--nosuffix] [-o|--options [+]Field1[,Field2...]] [-O|--sort [+|-]Key1[,[+|-]Key2...]] [-P|--partial] [--rows] [--separator Separator] [--unbuffered] [--units hHbBsSkKmMgGtTpPeE] [--unquoted] [-v|--verbose] [--version] [VolumeGroupName [VolumeGroupName...]]

DESCRIPTION

vgs produces formatted output about volume groups.

OPTIONS

See lvm(8) 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, vg_mda_used_count.

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.
