[OpenAFS] Replication

[Chris Snyder]

We're currently running a small OpenAFS system with a single server. I'm 
currently researching what it would take to add a second server for 
reliability purposes. This is mainly to ensure uptime of our web sites, which 
are stored on AFS. I'd like to have the second server be a read-only mirror 
of the master, updated automatically. That way, if the master goes down, the 
web server can still get access to the web site files, albeit read-only 
(which isn't much of a problem).

I'd like to use replication to accomplish this. As far as I can tell, 
replication has to be done manually. Is there a way to have replication be 
done automatically other than a cron job? If a cron job is the only method, 
will the performance of the servers suffer at all during the replication? 
Thanks in advance.
