DESCRIPTION

       vgs produces formatted output about volume groups.

OPTIONS

       See lvm(8) for common options.

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

       --aligned
              Use with --separator to align the output columns.

       --binary
              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).

       --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 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 missing 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 selection.  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 Selection 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 supported 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.

       --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.
