How is that any different?  Both sets of order constraints are identical, and look correct.  Changing the order you add them in makes no difference, as the rules are evaluated as a set, and the crm shell will reorder them in alphabetical (ASCIIbetical, actually) order anyway.

Frank, I see you have multipath in your LVM config.  Have you tried it with multipath disabled?  I wonder if this isn't a pacemaker/corosync problem but rather a lower-level storage problem.  Still, whatever the cause, it doesn't fill me with confidence about upgrading to SLES 11 SP2... I guess it's time to bring up that test cluster I've been meaning to build.
