       vgs produces formatted output about volume groups.


       See lvm for common options.

       --all  List all volume groups.  Equivalent to not specifying any volume

              Use with --separator to align the output columns.

              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 default selection of columns.

              Use -o vg_all to select all volume group columns.

              Use -o help to view the full list of columns available.

              Column   names   include:  vg_fmt,  vg_uuid,  vg_name,  vg_attr,
              vg_size,  vg_free,  vg_sysid,  vg_extent_size,  vg_extent_count,
              vg_free_count,  max_lv,  max_pv, pv_count, lv_count, snap_count,
              vg_seqno, vg_tags, vg_mda_count, vg_mda_free, and vg_mda_size.

              Any "vg_" prefixes are optional.  Columns  mentioned  in  either
              pvs  (8)  or  lvs  (8) can also be chosen, but columns cannot be
              taken from both at the same time.

              The vg_attr bits are:

              1  Permissions: (w)riteable, (r)ead-only

              2  Resi(z)eable

              3  E(x)ported

              4  (p)artial: one or more  physical  volumes  belonging  to  the
                 volume group are missing from the system

              5  Allocation    policy:    (c)ontiguous,   c(l)ing,   (n)ormal,
                 (a)nywhere, (i)nherited

              6  (c)lustered

       -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

              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.
