FreeBSD doesn't have a defined method of replicating data between two servers, for HA/DR purposes, similar to Veritas Volume Replicator. Linux has DRDB (http://www.drbd.org/) which isn't quite the same, and someone has tried using gmirror and ggate to have a mirror across teo systems, but neither of those can cope well with a disconnected network, or a slow network link. I was wondering if there would be any interest in creating a new geom provider to solve this problem. I can see that questions about this functionality have been asked on the mailing lists before, and I've drawn up some initial thoughts aand ideas at http://www.hmallett.co.uk/computing-mainmenu-49/72-computing/124-open-source-replicated-filesystems.html Hywel Mallett
