I don't know if the following is relevant to your problem (I don't have the 
full context here), but:

LVM defaults have been changed recently. If there is a file in 
/etc/lvm/devices, all vg…/lv… commands just use those partitions which are 
listed in that file. All other partitions, specifically those which are new in 
a system, are not included in the processing. You either have to add the device 
to that list or use an option in any of those commands.
