I'm using DRBD 0.7.14 with Xen (Debian Etch) right now on top of some LVM Logical Volumes: works great! No more out of date backups and fiddling around with rsync and snapshots (which have a great impact on the performance of services)!
Only thing to solve is Xen live migration between two servers, which is not very easy in DRBD 0.7... It seems that DRBD 0.8 supports running in primary/primary mode?
Works great
