.SH DESCRIPTION
lvs produces formatted output about logical volumes.
.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 instead of replacing it.
.IP
Use \fb-o lv_all\fP to select all logical volume columns, and \fb-o seg_all\fP
to select all logical volume segment columns.
.IP
Use \fb-o help\fP to view the full list of columns available.
.IP
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, origin_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.
.IP
With \-\-segments, any "seg_" prefixes are optional; otherwise any "lv_"
prefixes are optional.  Columns mentioned in \fBvgs (8)\fP 
can also be chosen.
.IP
The lv_attr bits are: 
.RS
.IP 1 3
Volume type: (m)irrored, (M)irrored without initial sync, (o)rigin, (p)vmove,
(s)napshot, invalid (S)napshot, (v)irtual, mirror (i)mage, mirror (I)mage
out-of-sync, under (c)onversion
.IP 2 3
Permissions: (w)riteable, (r)ead-only
.IP 3 3
Allocation policy: (c)ontiguous, c(l)ing, (n)ormal, (a)nywhere, (i)nherited
This is capitalised if the volume is currently locked against allocation
changes, for example during \fBpvmove\fP (8).
.IP 4 3
fixed (m)inor
.IP 5 3
State: (a)ctive, (s)uspended, (I)nvalid snapshot, invalid (S)uspended snapshot,
mapped (d)evice present without tables, mapped device present with (i)nactive table
.IP 6 3
device (o)pen
.RE
.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 \-\-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.
