ABSTRACT:
A computer implemented method, data processing system, and computer program product for maintaining state consistency among multiple state-driven file system entities when the file system entities become disconnected. Responsive to a distributed file system server being disconnected from a distributed file system client, a monitor is registered with the consistency management framework (CMF) for a file system. When the CMF detects access to a file in the file system, the CMF notifies the monitor of the access to the file, and the monitor stores information about state of the file. When the distributed file system server is reconnected to the distributed file system client, information about state of the file stored in the monitor is provided to the distributed file system client.
