[OpenAFS] about failover - 2 servers (one "master" one replicas) - a bit long

Create r/o replicas on A (and on the same vice partition), too.
The problem with your setup is that OpenAFS clients use the r/o path to acc=
data in replicated volumes, but you have put all your r/o replicas on one=20
single machine, so you have created a single point of failure.
You should also balance your r/w volumes between both servers.

OpenAFS is not designed for automatic failover.
