DESCRIPTION

       lvs produces formatted output about logical volumes.

OPTIONS

       See lvm for common options.

       --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 replac-
	      ing it.  Column names are: lv_uuid, lv_name, lv_attr, lv_major, lv_minor, lv_kernel_major, lv_kernel_minor, lv_size, seg_count, ori-
	      gin, 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,  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 hsbkmgtHKMGT
	      All sizes are output in these units: (h)uman-readable, (s)ectors, (b)ytes, (k)ilobytes, (m)egabytes, (g)igabytes, (t)erabytes.  Cap-
	      italise to use multiples of 1000 (S.I.) instead of 1024.	Can also specify custom (u)nits e.g.  --units 3M

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