DRBD disk backends can be used instead of tapdisk backends for Remus. This requires a Remus style disk replication protocol (asynchronous replication with output buffering at backup), that is not available in standard DRBD code. A modified version that supports this new replication protocol is available from git://aramis.nss.cs.ubc.ca/drbd-8.3-remus Use of DRBD disk backends provides a means for efficient resynchronization of data after the crashed machine comes back online. Since DRBD allows for online resynchronization, a DRBD backed Remus VM does not have to be stopped or shutdown while the disks are resynchronizing. Once resynchronization is complete, Remus can be started at will. Signed-off-by: Shriram Rajagopalan <rshriram@cs.ubc.ca> Committed-by: Ian Jackson <ian.jackson@eu.citrix.com>
