DESCRIPTION¶
vgs 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
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.
