Coordinator ownership authentication in a distributed system with multiple storage object coordinators
Abstract:
Exemplary methods, apparatuses, and systems include a replica node storing a component of a storage object detecting that a primary coordinator for the storage object component is no longer available to serve as primary coordinator. The replica node is within a cluster of nodes storing components of the storage object. In response to detecting that the primary coordinator is no longer available, the replica node updates a first metadata entry indicating that a secondary coordinator for the storage object component is unhealthy. The replica node rejects connection requests from the secondary coordinator in response to the first metadata entry indicating that the secondary coordinator for the storage object component is unhealthy.
