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.
