I can't find the drbd link. We use it at work ( or rather want
to use it), and I'm collecting info on it.
It is really cool. DRBD is basically software mirroring of two disks.
Add HA-NFS and you have a system that can handle live failover of an
NFS server ( NFS, really. I'm not making this up).
Once the primary comes back, the software resynchs any data that changed
on the disk.
