Possibly a starting point for automating LVM device permissions setting is https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Logical_Volume_Manager_Administration/udev_device_manager.html and in particular the possibility to add, under /lib/udev/rules, a customized file based on the one found in /usr/share/doc/device-mapper/12-dm-permissions.rules Not tried myself though...
