Abstract
A computer-implemented method for managing cluster node connectivity information. The method may include maintaining a set of cluster nodes of a clustered application. The method may also include, for each node in a set of cluster nodes, determining a connectivity state of the cluster node and transmitting, from the cluster node to non-volatile Random Access Memory ('RAM') of a cluster disk, connectivity information that indicates the connectivity state of the cluster node. The method may further include accessing, from a remote system, the non-volatile RAM of the cluster disk to retrieve connectivity information of one or more cluster nodes from the set of cluster nodes. The method may include using the connectivity information to inform the remote system of the connectivity state of the one or more cluster nodes. Various other methods, systems, and computer-readable media are also disclosed.
