DESCRIPTION
       lvs produces formatted output about logical volumes.

OPTIONS
       See lvm for common 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 creat‐
	      ing  a mirror using 'lvcreate -m1 --mirrorlog disk', this option
	      will reveal three internal Logical Volumes, with	suffixes  mim‐
	      age_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_path,  lv_attr,
	      lv_major,	 lv_minor,  lv_read_ahead,  lv_kernel_major,   lv_ker‐
	      nel_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 dur‐
		 ing 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  col‐
	      umns 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.
