Implementing data management application programming interface access rights in a parallel file system
First Claim
1. 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.

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.
