Abstract
Methods and structure are provided for rebuilding cache data from a failed cache device based on tracking data for the failed cache device. The system includes a memory and a cache manager. The memory stores tracking data that correlates entries at a cache with logical block addresses of a logical volume. The cache manager is able to determine that a device implementing the cache has failed and to analyze the tracking data to identify logical block addresses correlated with cache entries from the failed cache device. The cache manager is further able to generate new cache entries at a new cache device, and to populate the new cache entries with data from the identified logical block addresses.
