Has anyone been able to successfully make a cross-replicating file system with DRBD? I have two different use cases: 1) a file system to store a cache of credentials that can be written to and read from by two active Xen instances, one on physical machine A and the other on physical machine B. The file cache could be on either machine or on a third machine if necessar. 2) A file system to be the back end for a stateful Web Services server, with a second mirrored file system being kept up such that if the first one goes down, the second one can mount it and pick it up by means of linux-HA heartbeat or some other failover mechanism. If anyone has successfully managed to blend the DRBD modules with the Xen patches, please let me know.
