Abstract
In one or more embodiments of the invention, communication among host agents providing high availability in a computer cluster is implemented by reading and writing to files on a shared data store. Each host agent holds a lock on a file on the shared data store corresponding to a liveness indicator for the host agent and a coordinator host agent periodically monitors the liveness indicators for host failures.
