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).
- --configreport ReportName
- Make any subsequent -o, --options, -O, --sort or -S,
--select to apply for ReportName where ReportName is
either 'vg' for command's main report or 'log' for log report. If
--configreport option is not used to identify a report, then
command's main report is assumed. The log report is available only if
enabled by log/report_command_log lvm.conf(5) setting or if
--logonly option is used.
- --logonly
- Suppress the vgs report itself and display only log report on output.
- --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.
