Abstract: In a cluster of computing nodes having shared access to one or more volumes of data storage using a parallel file system, a method for managing the data storage includes initiating a data management application in the cluster using a data management application programming interface (DMAPI) of the parallel file system. When a request submitted to the parallel file system is received on one of the nodes to perform an operation on a file in one of the volumes of data storage, a data management access right is obtained from the DMAPI responsive to the request The operation is performed on the file using the access right.

Abstract: In a cluster (20) of computing nodes (22) having shared access to one or mor e volumes of data storage (24) using a parallel file system (28), a method for managing the data storage includes initiating a session of a data management application (32) on a first one of the nodes (40), while running a user application (30) on a second one of the nodes (42). A request is submitted t o the parallel file system by the user application on the second node to perfo rm a file operation on a file in one of the volumes of data storage. A data management event message is sent from the second node to the first node responsive to the request, for processing by the data management application on the first node.
