Hi
Wondering if there are known tools out there for doing block level replication of linux systems? There is a product for windows called Double Take that seems quite good but doe not work with Linux. Anyone know?
thanks
Sounds like maybe a SAN setup rather than some sort of software replicating data between two boxes.

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.
As others told you... use drbd for block device replication ( http://www.drbd.org ). You can use drbd and drbd kernel module included in CentOS Extras.
