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.

Abstract: A shared storage system 100 is in communication with one or more clusters 120 of host nodes 121-124. Access to the storage system is controlled by: storing cluster membership metadata 141 in a centralized storage 140 independent of the shared storage; updating the cluster membership metadata in response to an inclusion or exclusion request from a node identifying one or more nodes to include or exclude from a cluster; and managing access to storage volumes in the shared storage in response to each update to the cluster membership metadata. The method may also include resolving conflicting requests to update the cluster membership metadata. Responding to an exclusion request may include purging the shared storage of traffic from the excluded node, and/or establishing a fence to deny future access. The storage system does not have to rely on processing and maintaining a cluster membership list per logical unit, reducing system complexity, and provides a tie-breaking function.
