IIRC, this thread started when somebody was being advised *not* to use the /dev/mapper path, but rather to use the /dev/vg path. If there is special case handling in util-linux, why isn't it returning what is being advertised as the preferable path to use rather than the one that is said to be internal and not to be referenced? _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
