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