[OpenAFS] Failover

[Pierre Ancelot]

Well, thanks for the link to drdb, it's certainly what i'll use, this or
lustre. About the shared raid drive, if the server that runs it dies, i'
out anyways, so this is not failover.


Thanks. 
Pierre.

PS: Can you please stop to send to me cc to the mailing list ? it's
really annoying. Thanks.
