Abstract:
1. In a cluster of computing nodes having shared access to one or more volumes of data storage using a parallel file system, which is a physical file system that runs on the cluster of nodes and enables all the nodes in the cluster to access the same file data concurrently, a method for managing the data storage, comprising: selecting a first one of the nodes to serve as a session manager node; selecting a second one of the nodes to serve as a session node for a data management application to run on the one or more volumes of data storage using the parallel file system; creating a session of the data management application on the session node by sending a message from the session node to the session manager node, causing the session manager node to distribute information regarding the session among the nodes in the cluster; and responsive to the information distributed by the session manager node, receiving events at the session node from the nodes in the cluster when the nodes access the one or more volumes of data storage using the parallel file system, for processing by the data management application.
