DESCRIPTION
       lvs produces formatted output about logical volumes.

OPTIONS
       See lvm(8) for common options.

       --aligned
	      Use with --separator to align the output columns.

       --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.

       --binary
	      Use binary values "0" or "1" instead of descriptive literal val-
	      ues for columns that have exactly two  valid  values  to	report
	      (not  counting  the "unknown" value which denotes that the value
	      could not be determined).

       --configreport  ReportName
	      Make any subsequent -o, --options, -O, --sort or -S, --select to
	      apply  for  ReportName  where ReportName is either 'lv' for com-
	      mand's main report or 'log' for log report.   If	--configreport
	      option  is  not  used  to identify a report, then command's main
	      report is assumed. The log report is available only  if  enabled
	      by  log/report_command_log  lvm.conf(5)  setting or if --logonly
	      option is used.

       -H ,  --history
	      Include historical logical volumes in the output.	 (This has  no
	      effect  unless logical volumes were removed while the configura-
	      tion setting metadata/record_lvs_history was enabled.)

       --logonly
	      Suppress the lvs report itself and display only  log  report  on
	      output.

       --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 current list of  col-
	      umns,  '-'  to remove from the current list of columns or '#' to
	      compact given columns. The -o option can be repeated,  providing
	      several lists. These lists are evaluated from left to right.

	      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:  chunk_size,  convert_lv,	 copy_percent,
	      data_lv,	devices,  discards, lv_attr, lv_host, lv_kernel_major,
	      lv_kernel_minor,	 lv_kernel_read_ahead,	 lv_major,   lv_minor,
	      lv_name,	lv_path,  lv_profile, lv_read_ahead, lv_size, lv_tags,
	      lv_time, lv_uuid,	 metadata_lv,  mirror_log,  modules,  move_pv,
	      origin,	  origin_size,	   pool_lv,    raid_max_recovery_rate,
	      raid_min_recovery_rate,  raid_mismatch_count,  raid_sync_action,
	      raid_write_behind,      region_size,     segtype,	    seg_count,
	      seg_pe_ranges, seg_size, seg_size_pe,  seg_start,	 seg_start_pe,
	      seg_tags,	  snap_percent,	 stripes,  stripe_size,	 sync_percent,
	      thin_count, transaction_id, zero.

	      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: (C)ache, (m)irrored, (M)irrored without  initial
		 sync,	(o)rigin,  (O)rigin  with  merging  snapshot,  (r)aid,
		 (R)aid without initial sync, (s)napshot, merging  (S)napshot,
		 (p)vmove,  (v)irtual,	mirror or raid (i)mage, mirror or raid
		 (I)mage out-of-sync, mirror (l)og device, under (c)onversion,
		 thin  (V)olume,  (t)hin  pool, (T)hin pool data, raid or pool
		 m(e)tadata or pool metadata spare.

	      2	 Permissions: (w)riteable, (r)ead-only, (R)ead-only activation
		 of non-read-only volume

	      3	 Allocation  policy:   (a)nywhere,  (c)ontiguous, (i)nherited,
		 c(l)ing, (n)ormal This is capitalised if the volume  is  cur-
		 rently	 locked against allocation changes, for example during
		 pvmove(8).

	      4	 fixed (m)inor

	      5	 State: (a)ctive, (h)istorical, (s)uspended,  (I)nvalid	 snap-
		 shot,	invalid (S)uspended snapshot, snapshot (m)erge failed,
		 suspended snapshot (M)erge failed,  mapped  (d)evice  present
		 without  tables, mapped device present with (i)nactive table,
		 thin-pool (c)heck needed, suspended thin-pool (C)heck needed,
		 (X) unknown

	      6	 device (o)pen, (X) unknown

	      7	 Target	 type:	(C)ache, (m)irror, (r)aid, (s)napshot, (t)hin,
		 (u)nknown, (v)irtual.	This groups logical volumes related to
		 the  same  kernel  target  together.  So, for example, mirror
		 images, mirror logs as well as mirrors themselves  appear  as
		 (m)  if  they	use  the  original device-mapper mirror kernel
		 driver; whereas the raid equivalents using the md raid kernel
		 driver	 all  appear  as  (r).	 Snapshots  using the original
		 device-mapper driver appear as (s); whereas snapshots of thin
		 volumes using the new thin provisioning driver appear as (t).

	      8	 Newly-allocated  data	blocks	are overwritten with blocks of
		 (z)eroes before use.

	      9	 Volume Health, where there  are  currently  three  groups  of
		 attributes identified:

		 Common ones for all Logical Volumes: (p)artial, (X) unknown.
		 (p)artial  signifies that one or more of the Physical Volumes
		 this Logical Volume uses is  missing  from  the  system.  (X)
		 unknown signifies the status is unknown.

		 Related   to	RAID   Logical	 Volumes:   (r)efresh  needed,
		 (m)ismatches exist, (w)ritemostly.
		 (r)efresh signifies that one or more of the Physical  Volumes
		 this RAID Logical Volume uses had suffered a write error. The
		 write error could be due to a temporary failure of that Phys-
		 ical  Volume or an indication that it is failing.  The device
		 should be refreshed or replaced. (m)ismatches signifies  that
		 the  RAID  logical  volume has portions of the array that are
		 not coherent.	Inconsistencies are detected by	 initiating  a
		 "check" on a RAID logical volume.  (The scrubbing operations,
		 "check" and "repair", can be performed on a RAID logical vol-
		 ume via the 'lvchange' command.)  (w)ritemostly signifies the
		 devices in a RAID 1 logical  volume  that  have  been	marked
		 write-mostly.

		 Related to Thin pool Logical Volumes: (F)ailed, out of (D)ata
		 space, (M)etadata read only.
		 (F)ailed is set if thin pool encounters serious failures  and
		 hence	no  further I/O is permitted at all. The out of (D)ata
		 space is set if thin pool has run out of data space.  (M)eta-
		 data  read  only  signifies that thin pool encounters certain
		 types of failures but it's still  possible  to	 do  reads  at
		 least, but no metadata changes are allowed.

		 Related to Thin Logical Volumes: (F)ailed.
		 (F)ailed  is  set  when related thin pool enters Failed state
		 and no further I/O is permitted at all.

	      10 s(k)ip activation: this volume is flagged to be skipped  dur-
		 ing activation.

       -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.

       -S, --select Selection
	      Display  only  rows  that match Selection criteria. All rows are
	      displayed with the additional "selected"	column	(-o  selected)
	      showing  1 if the row matches the Selection and 0 otherwise. The
	      Selection criteria are defined by specifying  column  names  and
	      their valid values (that can include reserved values) while mak-
	      ing use of supported comparison operators. See  lvm(8)  and  -S,
	      --select	description  for  more detailed information about con-
	      structing the Selection criteria. As a quick  help  and  to  see
	      full  list of column names that can be used in Selection includ-
	      ing the list of reserved values and the set of supported	selec-
	      tion operators, check the output of lvs -S help command.

       --segments
	      Use default columns that emphasize segment information.

       --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.
