If you upgrade to xen.org release of Xen then you can use the block-drbd script to specify by drbd resource name instead of device, but that's just fluff in stuff, and doesn't have anything to do with the ability to live migrate which is all handled by the allow-two-primaries option.
True. In my case : CentOS 5.3, incl. kernel-xen and heartbeat, Xen.org 3.x, DRBD 8.2. It works, but has no cookie-cutter howto.
Are you saying that we can only use block-drbd script with Xen 3.2 ?
It's really not so much the Xen version, but the distro.
It might work with the Xen 3.1 libraries too, but that's also irrelevant as CentOS/RHEL has decided to use the Xen 3.0.3 libraries (though they are using the Xen 3.1 hypervisor, go figure!).
How did you determine they are different versions?
Linbit wrote the block-drbd script for Xen 3.1 (maybe 3.2) and up, but definitely not pre-3.1.
For the definitive answer though I recommend posting on drbd-user. Someone there might even have a work-around to get it to work on earlier Xen libraries...
