Techniques for maintaining device coordination in a storage cluster system

A method comprising:

• exchanging, through a node of multiple nodes, indications of status of the multiple nodes, 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;
• analyzing the indications of status to determine a current status of the quorum;
• coordinating 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, the tie breaker node assigned a weighting value such that the tie breaker node is treated as comprising more than one node in determinations of whether there is availability of sufficient nodes of the multiple nodes to form the quorum and such that a vote by the tie breaker node is treated as comprising more than one vote in determining whether a majority of the nodes of the multiple nodes are able to perform a coordinated operation;
• analyzing the indications of status to determine whether the first node has failed;
• and
• reassigning service from the first node to a second node of the multiple nodes in response to a determination that the first node has failed.

At least one non-transitory computer readable medium having stored thereon instructions for performing a method comprising machine executable code which when executed by at least one machine, cause the machine to:

• exchange, through a node of multiple nodes of a storage cluster system, indications of status of the multiple nodes, 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;
• analyze the indications of status to determine a current status of the quorum;
• 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, the tie breaker node assigned a weighting value such that the tie breaker node is treated as comprising more than one node in determinations of whether there is availability of sufficient nodes of the multiple nodes to form the quorum and such that a vote by the tie breaker node is treated as comprising more than one vote in determining whether a majority of the nodes of the multiple nodes are able to perform a coordinated operation;
• analyze the indications of status to determine whether the first node has failed;
• and
• reassign service from the first node to a second node of the multiple nodes in response to a determination that the first node has failed.
