.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
|
|

.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
