I was able to hook rbd up through SCST's iSCSI driver to export a lun, through which I was able to discover and perform some I/O via the open-iscsi drivers. Looks like it's basically working, but I wanted to check who else might have been testing this and whether anybody's been integrating either SCST or the mainline kernel iSCSI target driver with ceph/rbd? One subject I was hoping to hear more about was how we can manage persistent reservations in the ceph environment, as vmware/hyperv applications require it for I/O fencing purposes among others. It'd be nice to have a seamless failover with PR in the case where a client is accessing a lun via a node which fails. I'll try to formalize what I've done and put a page up on the ceph wiki regarding integrating at least the SCST side with RBD.
