AFS does not provide a method for failover, in the strictest meaning of the word. A replicated volume residing on a different file server than the original volume, would be the closest to what I think you mean. Although replicating every volume in a cell is not recommended. So I doubt that will work as a total failover method.

If a file server dies the only way I am aware of restoring it is to rebuild it from backups stored on tape, or disk, or from a dump file.

Hi everyone :)

I wanted to know how afs is reacting in the case of a failover
cluster...
i use keepalived on linux and i wish to have a failover distributed
filesystem, like what happens if a replica dies or if the first server
dies ? ... And when it will get back up, what should i know about
re-synchronisation ?


Thanks, pierre
