SYNOPSIS

lvs [--aligned] [-d/--debug] [-h/-?/--help] [--ignorelockingfailure] [--noheadings] [--nosuffix] [-o/--options [+]Field[,Field]] [-O/--sort [+/-]Key1[,[+/-]Key2[,...]]] [-P/--partial] [--segments] [--separator Separator] [--unbuffered] [--units hsbkmgtHKMGT] [-v/--verbose] [--version] [VolumeGroupName [VolumeGroupName...]]  

DESCRIPTION

lvs produces formatted output about logical volumes.  

OPTIONS

See lvm for common options.
--aligned
Use with --separator to align the output columns.
--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. 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.
With --segments, any "seg_" prefixes are optional; otherwise any "lv_" prefixes are optional. Columns mentioned in vgs (8) can also be chosen. Use -o help to view the full list of fields available.
The lv_attr bits are:
1
Volume type: (m)irrored, (M)irrored without initial sync, (o)rigin, (p)vmove, (s)napshot, invalid (S)napshot, (v)irtual
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.
--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 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
