Re: [Linux-cluster] GFS2 and lvm

if you're not using LVM but ARE using multipath then you should set up user-friendly name or use a path from /dev/disk/by-*

Not really...

How do you ensure then that the device paths of the GFS filesystems
are the same on all nodes (as is required by the shared cluster.conf)?

A shared disk may appear as /dev/sda in one node, but as /dev/sdb on
another node, for example, dependent on hardware or configuration

Actually, this is not really true.  We have many GFS2 filesystems on a three node cluster and we don't use LVM.  It really depends on how you are mounting the filesystems.  You really need to mount them by LABEL, so the underlying disk identifiers becomes irrelevant.
