.SH OPTIONS
See \fB lvm\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
2004-11-12 18:59:09 +03:00
to the default selection of columns instead of replacing it. Column names are:
lv_uuid, lv_name, lv_attr, lv_major, lv_minor, lv_kernel_major, lv_kernel_minor,
lv_size, seg_count, origin, snap_percent,
copy_percent, move_pv, lv_tags,
segtype, stripes,
2007-01-19 01:33:24 +03:00
stripesize, chunksize, seg_start, seg_size, seg_tags, devices,
regionsize, mirror_log, modules.

With \- \- segments, any "seg_" prefixes are optional; otherwise any "lv_"
prefixes are optional. Columns mentioned in \fB vgs (8)\fP
2004-11-12 18:59:09 +03:00
can also be chosen.

changes, for example during \fB pvmove\fP (8).

.TP
.I \- \- segments
Use default columns that emphasize segment information.
.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
