Thread-topic: AW: [Xen-users] domU on sparse-file on ocfs2 on drbd(pri/pri): Isthere anyone running this successfully?
..Ok, but how do i share a blockdevice concurrently?
Do you think of open-iscsi?

But i thought, this SAN-"emulation" is a 1-to-n connection?
AFAIK i'll have to run a daemon that distributes the iscsi-device. If i am 
using drbd, i can't run this service on both nodes at the same time, am i right?

So how do i implement "shared block devies" in a way, that mirrors my images 
between two nodes for instant live migration?
