.SH DESCRIPTION
vgs produces formatted output about volume groups.
.SH OPTIONS
See \fBlvm\fP for common options.
.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.  Column names are: 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.
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.  
Use \fb-o help\fP to view the full list of fields available.
.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
.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 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
.TP
.I \-\-unquoted
When used with --nameprefixes, output values in the field=value pairs are not quoted.
