.SH DESCRIPTION
2004-11-12 18:59:09 +03:00
vgs produces formatted output about volume groups.
2002-12-12 23:55:49 +03:00
.SH OPTIONS
See \fB lvm\fP for common options.
.TP
.I \- \- aligned
Use with \- \- separator to align the output columns.
.TP
2009-01-20 20:10:44 +03:00
.I \- \- 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 \fB udev (7)\fP rules).
.TP
2002-12-12 23:55:49 +03:00
.I \- \- noheadings
Suppress the headings line that is normally the first line of output.
Useful if grepping the output.
.TP
.I \- \- nosuffix
Suppress the suffix on output sizes. Use with \- \- units (except h and H)
if processing the output.
.TP
.I \- o, \- \- options
Comma-separated ordered list of columns. Precede the list with '+' to append
Cleanup pvs, vgs, and lvs "-o" section in man pages (rhbz 500861).
http://bugzilla.redhat.com/show_bug.cgi?id=500861
- Update list of fields/columns for each command (a few missing).
- Update list order to match "-o help" output (easier to verify field list)
- Add "{pv|vg|lv}_all" description.
- Move "-o help" sentence above column/field list.
New sample man page for lvs (pvs and vgs are similar):
-o, --options
Comma-separated ordered list of columns. Precede the list with ’+’ to append to the
default selection of columns instead of replacing it.
Use -o lv_all to select all logical volume columns, and -o seg_all to select all logical
segment columns.
Use -o help to view the full list of columns available.
Column names include: lv_uuid, lv_name, lv_attr, lv_major, lv_minor, lv_read_ahead,
lv_kernel_major, lv_kernel_minor, lv_kernel_read_ahead, lv_size, seg_count, origin, ori-
gin_size, snap_percent, copy_percent, move_pv, convert_lv, lv_tags, mirror_log, modules,
segtype, stripes, stripesize, regionsize, chunksize, seg_start, seg_start_pe, seg_size,
seg_tags, seg_pe_ranges, devices.
With --segments, any "seg_" prefixes are optional; otherwise any "lv_" prefixes are
optional. Columns mentioned in vgs (8) can also be chosen.
The lv_attr bits are:
2009-06-15 21:09:32 +04:00
to the default selection of columns.
.IP
Use \fb -o vg_all\fP to select all volume group columns.
.IP
Use \fb -o help\fP to view the full list of columns available.
.IP
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, max_lv, max_pv,
pv_count, lv_count, snap_count, vg_seqno, vg_tags, vg_mda_count, vg_mda_free,
and vg_mda_size.
.IP
2002-12-12 23:55:49 +03:00
Any "vg_" prefixes are optional. Columns mentioned in either \fB pvs (8)\fP
or \fB lvs (8)\fP can also be chosen, but columns cannot be taken from both

at the same time.

.TP
.I \- 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.
.TP
2009-01-20 19:55:24 +03:00
.I \- \- rows
Output columns as rows.
.TP
2002-12-12 23:55:49 +03:00
.I \- \- separator Separator
String to use to separate each column. Useful if grepping the output.
.TP
.I \- \- unbuffered
Produce output immediately without sorting or aligning the columns properly.
.TP
.I \- \- 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
2009-01-20 20:39:07 +03:00
.TP
.I \- \- unquoted
When used with --nameprefixes, output values in the field=value pairs are not quoted.
