Mondo rescue?
thanks but i want box b to be at the other end of a LAN extension and whenever any block gets updated on box i want that replicated on box b
i want absolute block for block as opposed to using something like rsync
Look at http://www.linux-ha.org/ and in particular the part about drbd which manages the block level replication. You can also roll your own using the enbd device and software raid. I'd also think that you should be able to do software raid over iscsi but haven't seen anything about it yet.
