System and method for coordinating cluster serviceability updates over distributed consensus within a distributed data system cluster

A distributed data system cluster may include several nodes and an interconnect coupling the nodes. Each node may include a consensus module and a serviceability module. In response to receiving a request to perform a serviceability update from a serviceability module, a consensus module may be configured to send a vote request to the consensus modules included in each of the other nodes. Each consensus module may be configured to send a vote to each other consensus module in response to receiving the vote request. A consensus module in one may also be configured to cause a serviceability module included in the same node to perform the serviceability update dependent on whether a quorum is indicated by the votes received from the consensus modules in the other nodes.
