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 ?
AFS is not a high availability cluster file system. (It's at least
not it's primary design target)
The replication in AFS is just for read-only data, and is actually
designed
for being able to distribute the same (read-only) information on more
fileservers all over the world.
That's why the replication has to be triggered by the administrator.
This might _not_ be what you mean by failover.
The keepalive is completely irrelevant in this case, since there is
no synchronization
other than the one triggered by the admin.
If you can specify, what you're planning to do, maybe somebody on the
list will be able to help you further.
