replica-set

I have three servers with mongod installed on it running as a replication set. Suddenly the two secondories became unavailable (the mongod process died) - I think because they were too stale.

The problem is that the original PRIMARY is now the SECONDARY and my application doesn't work because it can't connect to a PRIMARY.

I mean, in which way does that help me? If the replica set can't do failover?! Am I missing something?

Furhtermore I am asking myself why did the SECONDARIES die / why are they too stale? What can I do about it?

FYI: My database is quite big (40GB on disk).

Is it true that a mongoDB configured as a replicaset (lets say two nodes + an arbiter) will always be slower than the same DB and server specs but configured as a Master?
