.SH DESCRIPTION
2004-11-12 18:59:09 +03:00
lvs produces formatted output about logical volumes.
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:

.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
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
2009-07-07 23:28:57 +04:00
.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
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.
