Automated node fencing integrated within a quorum service of a cluster infrastructure

A system for managing quorum services in a cluster infrastructure for reliable failover of shared resources, comprising:

• a quorum service implemented in a cluster environment on at least one processor coupled to at least one memory;
• the quorum service for automatically triggering at least one automated fencing operation within a cluster infrastructure layer of the cluster environment comprising a plurality of nodes to reliably maintain a node usability state of each node of the plurality of nodes indicating an availability of each node to control and access at least one shared resource of the cluster;
• and
• the quorum service for reporting the node usability state of each node as a cluster health status to at least one distributed application within an application layer of the cluster environment, to provide a reliable cluster health status of the plurality of nodes to the at least one distributed application for a failover of said at least one shared resource from control by a failed node from among the plurality of nodes to another node from among the plurality of nodes.

A computer program product for managing quorum services in a cluster infrastructure for reliable failover of shared resources, said computer program product comprising:

• one or more computer-readable tangible storage devices;
• program instructions, stored on at least one of the one or more storage devices, to automatically trigger at least one automated fencing operation by a quorum service within a cluster infrastructure layer of a cluster environment comprising a plurality of nodes to reliably maintain a node usability state of each node of the plurality of nodes indicating an availability of each node to control and access at least one shared resource of the cluster;
• and
• program instructions, stored on at least one of the one or more storage devices, to report, by the quorum service, the node usability state of each node as a cluster health status to at least one distributed application within an application layer of the cluster environment, to provide a reliable cluster health status of the plurality of nodes to the at least one distributed application for a failover of said at least one shared resource from control by a failed node from among the plurality of nodes to another node from among the plurality of nodes.
