vgs
produces formatted output about volume groups.
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
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
- 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.
- -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 Selection 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 supported 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. 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.
