 NAME    [Toc]    [Back]
      lvmpvg - LVM physical volume group information file

 SYNOPSIS    [Toc]    [Back]
      /etc/lvmpvg

 DESCRIPTION    [Toc]    [Back]
      lvmpvg is an ASCII file that stores the volume-group information for
      all of the physical volume groups in the system.  The information is
      stored in a hierarchical format.

      First, it starts with a volume group under which multiple physical
      volume groups can exist.  Under each physical volume group, a list of
      physical volumes can be specified.  There must be at least one
      physical volume group in each volume group that appears in this file.
      The physical-volume-group name must be unique within the corresponding
      volume group, although it is permissible to use a common physical
      volume group name across different volume groups.  There can be as
      many volume groups in this file as there are in the system.

      Instead of using the vgcreate and vgextend commands, the administrator
      can edit this file to create and extend physical volume groups.
      However, care must be taken to ensure that all physical volumes to be
      included in the file have already been defined in their respective
      volume groups by previous use of vgcreate or vgextend.

      The lvmpvg file format has the following structure.  VG and PVG are
      keywords that introduce the names of the volume group and physical
      volume group, respectively.  No comments are allowed in this file.

           VG  vg_name
           PVG pvg_name
           pv_path
              ...
           PVG pvg_name
           pv_path
              ...
           VG  vg_name
           PVG pvg_name
           pv_path
              ...

      The variables are defined as follows:

           pv_path        The block device path name of a physical volume
                          within the volume group.

           pvg_name       The name of the physical volume group.  It must be
                          unique within the volume group.

           vg_name        The path name of the volume group.

 EXAMPLES    [Toc]    [Back]
      The following example shows an lvmpvg file containing two volume
      groups: the first containing two physical volume groups, each with two
      physical volumes defined in it; the second containing three physical
      volume groups, each with one physical volume defined in it.
