Split Brain Problem
807567May 18 2002 — edited May 24 2002In a clustered environment typically hosts are interconnected using network connection, and maintains record of each other health using heartbeat mechanism.
If network link between hosts is down then it splits the network in two halfs with each host assuming that it is the master of the network. Since there is no connection between the hosts they can't differentiate between the scenario where other host is down OR they have just lost their connectivity.
Any idea how to solve this issue or any books, references etc ? Your responses will be deeply appreciated.
