[-v|--verbose] [-a|--all] [-x|--allocatable y|n] [-u|--uuid] [PhysicalVolumePath...]
DESCRIPTION
pvchange allows you to change the allocation permissions of one or more physical volumes.

See lvm for common options.
-a, --all
If PhysicalVolumePath is not specified on the command line all physical volumes are searched for and used.

-u, --uuid
Generate new random UUID for specified physical volumes.
-x, --allocatable y|n
Enable or disable allocation of physical extents on this physical volume.
Example
"pvchange -x n /dev/sdk1" disallows the allocation of physical extents on this physical volume (possibly because of disk errors, or because
it will be removed after freeing it.
