Is there a layer2 link between the two locations? If yes you can use sheepdog. pro and con, example sheepdog configuration is much simpler then DRBD sheepdog works with much nodes, DRBD supports only 2 master-master nodes sheepdog works well for virtualization qemu/kvm, DRBD is better for gfs or ocfs2 and physical hardware sheepdog != DRBD, sheepdog more like ceph RBD Cheers Jens |
