.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 \-\-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.  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,
stripesize, chunksize, seg_start, seg_size, seg_tags, devices,
regionsize, mirror_log, modules.
.IP
With \-\-segments, any "seg_" prefixes are optional; otherwise any "lv_"
prefixes are optional.  Columns mentioned in \fBvgs (8)\fP 
can also be chosen.
Use \fb-o help\fP to view the full list of fields available.
.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
.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 \-\-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
