At first you should make a backup of your administrativ databases of your last 
running server (kaserver.DB*, prdb.DB*, vldb.DB* (,bdb.DB* - if you have it))

Then you can install a new OS on your broken machine. But _do not start_ 

Copy some files manually from your last server left to your reinstalled 
server, which are:


(/usr/afs might be at a different location)

Then you can start the afs-processes on your reinstalled server.

Then you can use "udebug <server> <portnumber>" to watch the databases 
synchronize. Ports are in range 7002-7004.

Good Luck
