System and Method of Rebuilding READ Cache for a Rebooted Node of a Multiple-Node Storage Cluster

A storage system, comprising:

• a storage cluster including a plurality of storage devices;
• a plurality of nodes in communication with the storage cluster;
• a cache memory for at least one node of the plurality of nodes, the cache memory including a first cache data associated with data transferred between the at least one node and regions of the storage cluster receiving at least a first selected number of data transfer requests, and further including a first cache metadata associated with the regions of the storage cluster receiving at least the first selected number of data transfer requests;
• and
• a cache manager in communication with the cache memory, the cache manager configured to store a second cache data in the cache memory when the at least one node is rebooted, the second cache data being associated with data transferred between the at least one node and one or more of the regions of the storage cluster receiving at least a second selected number of data transfer requests after the at least one node is rebooted, wherein the second selected number of data transfer requests is less than the first selected number of data transfer requests.
