vgs produces formatted output about volume groups.
See lvm for common options.
- --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. Column names are: 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.
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. Use -o help to view the full list of
fields available.
- The vg_attr bits are:
- 1
- Permissions: (w)riteable, (r)ead-only
- 2
- Resi(z)eable
- 3
- E(x)ported
- 4
- (p)artial
- 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 hsbkmgtHKMGT
- All sizes are output in these units: (h)uman-readable, (s)ectors, (b)ytes,
(k)ilobytes, (m)egabytes, (g)igabytes, (t)erabytes. Capitalise to use
multiples of 1000 (S.I.) instead of 1024. Can also specify custom (u)nits
e.g. --units 3M
- --unquoted
- When used with --nameprefixes, output values in the field=value pairs are
not quoted.
