       vgs — report information about volume groups

       vgs produces formatted output about volume groups.

       See lvm(8) for common options.

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

              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).

              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 vari‐
              ables (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 process‐
              ing 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 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,  vg_profile,  max_lv,
              max_pv,  pv_count,   lv_count,   snap_count,   vg_seqno,   vg_tags,   vg_mda_count,
              vg_mda_free, and vg_mda_size, vg_mda_used_count.

              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  miss‐
                 ing from the system

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

              6  (c)lustered, (s)hared

       -O, --sort
              Comma-separated  ordered  list  of columns to sort by.  Replaces the default selec‐
              tion. 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 Selec‐
              tion 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 sup‐
              ported 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 vgs -S help command.

       --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.  Capi‐
              talise 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
