NAME
lvmpvg — LVM physical volume group information file
DESCRIPTION
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
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.
