No. There are two symmetric systems, and when primary server can't
start, secondary activates it's own fbserver, and after playing a bit
with IP addresses clients even do not notice, that they work with
another box.
But such ideal scenario worked only once (last time). Earlier bugs in
the system forced me to go and do manual recovery. It is anyway required
to make system comletely functional again, but such pair of servers help
people to continue there work after the failure almost immediately.
