So, in your Xen configs, are you using phy: to access the DRBD devices directly?  If so, then you should be okay without a cluster-aware filesystem - sorry about that, I was under the impression that you were mounting the DRBD device on the dom0s and then storing disk files on it.

I was not really correct - there is no filesystem at all in my drbd
devices:

The same at hostb.
So. my drbd devices contain partitions, and these partitions contain a
filesystem (ext3 and swap, in my case)

Now I am really confused :-)
Should I switch to drbd-user mailing list?
