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, vg_profile, 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.
