Implementing data management application programming interface access rights in a parallel file system

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, comprising:

• creating a session of a data management (DM) application on a session node selected from among the nodes in the cluster by invoking a function of a data management application programming interface (DMAPI) of the parallel file system;
• receiving a request submitted to the parallel file system by a user application on a source node in the cluster to perform an operation on a file in one of the volumes of data storage;
• sending a notification of a DM event from the source node to the session node responsive to the request;
• obtaining a data management access right from the DMAPI by processing the event at the session node;
• and
• performing the operation on the file from the source node using the access right.
