Data management application programming interface handling mount on multiple nodes in a parallel file system
First Claim
1. In a cluster of computing nodes having shared access to one or more file systems in data storage using parallel file system software, a method for managing the data storage, comprising:
- initiating a session of a data management application on a first one of the nodes;
receiving a request submitted to the parallel file system software at a second one of the nodes to mount one of the file systems in the data storage on the second one of the nodes; and
sending a mount event message from the second node to the first node responsive to the request, for processing by the data management application on the first node.

Abstract
In a cluster of computing nodes having shared access to one or more file systems in data storage using parallel file system software, a method for managing the data storage includes initiating a session of a data management application on a first one of the nodes, while running a user application on a second one of the nodes. A request is submitted to the parallel file system software by the user application on the second node to mount one of the file systems in the data storage. A mount 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. When the file system is to be unmounted, preunmount and unmount events are sent for processing by the data management application on the first node.

23. Computing apparatus, comprising:
-
one or more volumes of data storage, arranged to store data in one or more file systems; and
a plurality of computing nodes, linked to access the volumes of data storage using parallel file system software, and arranged so as to enable a data management application to initiate a data management session on a first one of the nodes, so that when a request is submitted to the parallel file system software at a second one of the nodes to mount one of the file systems in the data storage on the second one of the nodes, a mount 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.

45. A computer software product for use in a cluster of computing nodes having shared access to one or file systems in data storage, accessed using parallel file system software, the product comprising a computer-readable medium in which program instructions are stored, which instructions, when read by the computing nodes, cause a session of a data management application to be initiated on a first one of the nodes, and in response to a request submitted to the parallel file system software at a second one of the nodes to mount one of the file systems in the data storage on the second node, cause the second node to send a mount event message to the first node, for processing by the data management application on the first node.
