Cluster-wide service agents

A method, comprising:

• assigning a first agent, deployed to a first node, as a master agent configured to actively process cluster service API calls and a second agent, deployed to a second node, as a standby agent, wherein the first agent and the second agent comprise an acquire master duties interface used to be assigned as the master agent and a release master duties interface used to relinquish assignment from being the master agent;
• reassigning the second agent as the master agent, wherein the first agent executes the release master duties interface to relinquish assignment from being the master agent and the second agent subsequently executes the acquire master duties interface to being assigned as the master agent for processing the cluster service API calls to a set of storage cluster services;
• and
• instructing the second agent, as the master agent, to perform a clean-up of prior cluster service API call processing that was in progress by the first agent before the reassignment.

A non-transitory computer readable medium comprising instructions that, when executed by a processor, cause the processor to:

• assign a first agent, deployed to a first node, as a master agent configured to actively process cluster service API calls and a second agent, deployed to a second node, as a standby agent, wherein the first agent and the second agent comprise an acquire master duties interface used to be assigned as the master agent and a release master duties interface used to relinquish assignment from being the master agent;
• reassign the second agent as the master agent, wherein the first agent executes the release master duties interface to relinquish assignment from being the master agent and the second agent subsequently executes the acquire master duties interface to being assigned as the master agent for processing the cluster service API calls to a set of storage cluster services;
• and
• instruct the second agent, as the master agent, to perform a clean-up of prior cluster service API call processing that was in progress by the first agent before the reassignment.
