Abstract:
According to one aspect of the present disclosure, a method and technique for hierarchical network failure handling in a clustered node environment is disclosed. The method includes: detecting a network failure by a node in a cluster, the cluster having plural nodes arranged in a hierarchy, wherein the network failure is associated with a subordinate node in the hierarchy to the detecting node; communicating the network failure from the detecting node to a superior node in the hierarchy; determining whether the network failure affects nodes higher than the detecting node in the hierarchy; and responsive to determining that the network failure does not affect nodes higher than the detecting node in the hierarchy, the detecting node initiating a protocol to expel the subordinate node from the cluster.
