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 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 current list
of columns, '-' to remove from the current list of columns
or '#' to compact given columns. The -o option can
be repeated, providing several lists. These lists are evaluated
from left to right.
-
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, (s)hared
- -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.
