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
              creating  a  mirror  using  lvcreate -m1 --mirrorlog disk , this option will reveal
              three internal Logical Volumes, with suffixes mimage_0, mimage_1, and mlog.

       --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:  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_read_ahead,  lv_size,  lv_tags,  lv_time,
              lv_uuid,  metadata_lv,  mirror_log, modules, move_pv, origin, origin_size, pool_lv,
              region_size, segtype, seg_count, seg_pe_ranges, seg_size, seg_start,  seg_start_pe,
              seg_tags, snap_percent, stripes, stripe_size, 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: (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 thin pool m(e)tadata

              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

              6  device (o)pen

              7  Target  type:  (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  (p)artial:  One  or  more  of  the  Physical Volumes this Logical Volume uses is
                 missing from the system.

       -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.

       --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 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

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