.SH DESCRIPTION
|
|
lvs produces formatted output about logical volumes.
|
|
.SH OPTIONS
|
|
See \fBlvm\fP for common options.
|
|
.TP
|
|
.I \-\-all
|
|
Include information in the output about internal Logical Volumes that
|
|
are components of normally-accessible Logical Volumes, such as mirrors,
|
|
but which are not independently accessible (e.g. not mountable).
|
|
The names of such Logical Volumes are enclosed within square brackets
|
|
in the output. For example, after creating a mirror using 'lvcreate -m1
|
|
--mirrorlog disk', this option will reveal three internal Logical
|
|
Volumes, with suffixes mimage_0, mimage_1, and mlog.
|
|
.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_path, 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,
|
|
(O)rigin with merging snapshot, (s)napshot, merging (S)napshot, (p)vmove,
|
|
(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.
