DESCRIPTION
       lvs produces formatted output about logical volumes.

OPTIONS
       See lvm for common options.

       --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.  Column names are: lv_uuid, lv_name, lv_attr,
              lv_major, lv_minor, lv_kernel_major, lv_kernel_minor, lv_size,
              seg_count, origin, snap_percent, copy_percent, move_pv, lv_tags,
              segtype, stripes, stripesize, chunksize, seg_start, seg_size,
              seg_tags, devices, regionsize, mirror_log, modules.

              With --segments, any "seg_" prefixes are optional; otherwise any
              "lv_" prefixes are optional.  Columns mentioned in vgs (8) can
              also be chosen.  Use -o help to view the full list of fields
              available.

              The lv_attr bits are:

              1  Volume type: (m)irrored, (M)irrored without initial sync,
                 (o)rigin, (p)vmove, (s)napshot, invalid (S)napshot,
                 (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 hsbkmgtHKMGT
              All sizes are output in these units: (h)uman-readable,
              (s)ectors, (b)ytes, (k)ilobytes, (m)egabytes, (g)igabytes,
              (t)erabytes.  Capitalise to use multiples of 1000 (S.I.) instead
              of 1024.  Can also specify custom (u)nits e.g.  --units 3M

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