DESCRIPTIONvgs 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,
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 vol‐
ume 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 col‐
umns 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.
