TECHNIQUES FOR MAINTAINING DEVICE COORDINATION IN A STORAGE CLUSTER SYSTEM

摘要

Various embodiments are generally directed to techniques for maintaining and using a quorum of nodes within a cluster of a storage cluster system to perform coordinated operations. An apparatus includes a node of multiple nodes of a storage cluster system, each node to oversee a copy of client data and a first node to serve as a tie breaker node in determinations of whether there is a quorum; a quorum coordination component to determine a current status of the quorum, and coordinate performance of a coordinated operation among the multiple nodes to alter the copies of the client data based on the current status of the quorum; and a tie breaker reassignment component to analyze the indications to determine whether the first node has failed and reassign the tie breaker node from the first node to a second node in response to a determination that the first node has failed.

1. An apparatus comprising:
a processor component of a node of multiple nodes of a storage cluster system, each node of the multiple nodes to oversee storage of a separate copy of client data, and a first node of the multiple nodes to serve as a tie breaker node in determinations of whether there is availability of sufficient nodes of the multiple nodes to form a quorum; a network interface to couple the processor component to other nodes of the multiple nodes to enable exchanges of indications of status of the multiple nodes; a quorum coordination component to analyze the indications of status to determine a current status of the quorum, and to coordinate performance of a coordinated operation among the multiple nodes to alter the copies of the client data based on the current status of the quorum, including the tie breaker node; and a tie breaker reassignment component to analyze the indications of status to determine whether the first node has failed and to reassign service as the tie breaker node from the first node to a second node of the multiple nodes in response to a determination that the first node has failed.
