lvmpvg — LVM physical volume group information file




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:


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


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


The path name of the volume group.


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.

VG /dev/vg00 PVG PVG0 /dev/dsk/c2t0d0 /dev/dsk/c2t1d0 PVG PVG1 /dev/dsk/c3t0d0 /dev/dsk/c3t1d0 VG /dev/vg01 PVG PVG0 /dev/dsk/c4t0d0 PVG PVG1 /dev/dsk/c5t0d0 PVG PVG2 /dev/dsk/c6t0d0
