.SH DESCRIPTION
vgs produces formatted output about volume groups.
.SH OPTIONS
See \fBlvm\fP for common options.
.TP
.I \-\-all
List all volume groups.  Equivalent to not specifying any volume groups.
.TP
.I \-\-aligned
Use with \-\-separator to align the output columns.
.TP
.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 \fBudev (7)\fP rules).
.TP
.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
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
Any "vg_" prefixes are optional.  Columns mentioned in either \fBpvs (8)\fP 
or \fBlvs (8)\fP can also be chosen, but columns cannot be taken from both
at the same time.  
.IP
The vg_attr bits are:
.RS
.IP 1 3
Permissions: (w)riteable, (r)ead-only
.IP 2 3
Resi(z)eable
.IP 3 3
E(x)ported
.IP 4 3
(p)artial: one or more physical volumes belonging to the volume group
are missing from the system
.IP 5 3
Allocation policy: (c)ontiguous, c(l)ing, (n)ormal, (a)nywhere, (i)nherited
.IP 6 3
(c)lustered
.RE
.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
.I \-\-rows
Output columns as rows.
.TP
.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 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
.TP
.I \-\-unquoted
When used with --nameprefixes, output values in the field=value pairs are not quoted.
