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.
--binary
Use binary values "0" or "1" instead of descriptive literal values for columns that
have exactly two valid values to report (not counting the "unknown" value which
denotes that the value could not be determined).
--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 vari‐
ables (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 process‐
ing 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 miss‐
ing from the system
5 Allocation policy: (c)ontiguous, c(l)ing, (n)ormal, (a)nywhere
6 (c)lustered
-O, --sort
Comma-separated ordered list of columns to sort by. Replaces the default selec‐
tion. Precede any column with '-' for a reverse sort on that column.
--rows Output columns as rows.
-S, --select Selection
Display only rows that match Selection criteria. All rows are displayed with the
additional "selected" column (-o selected) showing 1 if the row matches the Selec‐
tion and 0 otherwise. The Selection criteria are defined by specifying column names
and their valid values (that can include reserved values) while making use of sup‐
ported comparison operators. See lvm(8) and -S, --select description for more
detailed information about constructing the Selection criteria. As a quick help and
to see full list of column names that can be used in Selection including the list
of reserved values and the set of supported selection operators, check the output
of vgs -S help command.
--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. Capi‐
talise 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.
