.SH OPTIONS
See \fBlvm\fP for common options.
.TP
.I \-\-aligned
Use with \-\-separator to align the output columns.
.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.
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.  The vg_attr bits are: (w)riteable, (r)eadonly, 
resi(z)eable, e(x)ported, (p)artial.
.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 \-\-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
