Update units_to_bytes() to support (S)ectors: 500 bytes. - 500 byte (S)ectors is of questionable value but it adds to consistency if a user happens to use --units S. This seems better than an error. Updated test/t-covercmd.sh to test --units [hS] Document the units that can be displayed via --units uniformly. - (p)etabytes and (e)xabytes were missing in pvs, vgs and lvs man pages. Made lvreduce man page "... in units of megabytes." consistent (with the lvextend and lvresize man pages).

.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.
