Some time back, LVM1 introduced persistent minors, so the minor number is 
stored on disk and remembered for subsequent activations.

In LVM2, persistent minors are optional and the default is *not* to use
them, so the minor number may be different each time a device is
activated, and no minor number is stored on disk.


IIRC Exporting the VG and then importing it again will reassign LVM1 
minor numbers.
