I don't have anything written up for it, and it hasn't really been tested with active users, but I do believe I have a working OpenAFS server setup with drbd (enbd would work fine, too).
There were a few tricks involved in setting it up. 1) I made sure that only my failover IP was being registered with the volume database using the NetInfo file (just put in the failover IP address in /usr/afs/local/NetInfo). 2) The big trick was forcing my takeover node to use the the failover IP address (which is an IP alias) as the source address on outgoing packets from that interface. See the attached heartbeat script (goes in /etc/ha.d/resource.d). The method I used is probably Linux-specific... 3) Finally, I had to make sure the machines were using the same ID (I used a hexeditor on the /usr/afs/local/sysid file, but maybe someone else has a better method). Both machines are database servers, with only the active file server running "fs" at any given time. They both have "fs" defined but not set to run automatically and bos is set to never restart the services (otherwise it would do the wrong thing). I think that was it, but I may have missed something. I might be able to help if you get stuck.
