Abstract:
A method, computer program product, and computer system for monitoring health of at least one storage device of a cache in a clustered system. A recovery journal may be maintained, wherein the recovery journal may identify whether one or more chunks of data stored in the cache have been dumped from the at least one storage device to persistent storage in the clustered system. A state of the at least one storage device may be determined based upon, at least in part, the health of the at least one storage device. A recovery action may be performed on the one or more chunks of data stored in the at least one storage device based upon, at least in part, the state of the at least one storage device.
