       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 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

              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) 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:  (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 output.

              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
