LVS

NAME

SYNOPSIS

DESCRIPTION

OPTIONS

--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.

--aligned

Use with --separator to align the output columns.

--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 udev (7) rules).

--noheadings

Suppress the headings line that is normally the first line of output. Useful if grepping the output.

--nosuffix

Suppress the suffix on output sizes. Use with --units (except h and H) if processing the output.

-o, --options

Comma-separated ordered list of columns. Precede the list with '+' to append to the default selection of columns instead of replacing it.

Use -o lv_all to select all logical volume columns, and -o seg_all to select all logical volume segment columns.

Use -o help to view the full list of columns available.

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.

With --segments, any "seg_" prefixes are optional; otherwise any "lv_" prefixes are optional. Columns mentioned in vgs (8) can also be chosen.

The lv_attr bits are:

1

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

2

Permissions: (w)riteable, (r)ead-only

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 pvmove (8).

4

fixed (m)inor

5

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

6

device (o)pen

--segments

Use default columns that emphasize segment information.

-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.

--rows

Output columns as rows.

--separator Separator

String to use to separate each column. Useful if grepping the output.

--unbuffered

Produce output immediately without sorting or aligning the columns properly.

--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

--unquoted

When used with --nameprefixes, output values in the field=value pairs are not quoted.
