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  Logi-
              cal  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.

       --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_kernel_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 during 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 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 spec-
              ify custom units e.g. --units 3M

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