Well, I'm upgrading a server from 5.8 to 6.3. Problem: someone built the system with LVM. I see some few differences between /etc/lvm/lvm.conf and the one from 6.3, and I'm trying to figure out what I can leave alone, and what I need to set to that from the old version. For example, the old one has preferred_names = [], and the new has a list. Anyone have thoughts about whether I can just copy over the old? I do know there are some new parameters (thin_*): do I need to add them? mark
