       lvs produces formatted output about logical volumes.


       See lvm(8) for common options.

              Use with --separator to align the output columns.

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

       --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.

              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).

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

              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
              columns,  '-'  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

              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
                 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,  snapshot  (m)erge  failed,  suspended
                 snapshot  (M)erge  failed,  mapped  (d)evice  present without
                 tables, mapped device  present  with  (i)nactive  table,  (X)

              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:  (p)artial,  (r)efresh  needed,  (m)ismatches
                 exist,  (w)ritemostly, (X) unknown.  (p)artial signifies that
                 one or more of the Physical Volumes this Logical Volume  uses
                 is  missing from the system.  (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 Physical 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 volume  via  the
                 'lvchange'  command.)  (w)ritemostly signifies the devices in
                 a RAID 1 logical volume that have been marked write-mostly.

              10 s(k)ip activation: this  volume  is  flagged  to  be  skipped
                 during 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
              making use of supported comparison operators. See lvm(8) and -S,
              --select   description   for  more  detailed  information  about
              constructing the Selection criteria. As a quick help and to  see
              full  list  of  column  names  that  can  be  used  in Selection
              including the list of reserved values and the set  of  supported
              selection operators, check the output of lvs -S help command.

              Use default columns that emphasize segment information.

       --separator Separator
              String  to  use to separate each column.  Useful if grepping the

              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

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