Abstract:
1. A method for performing one or more operations associated with a system restart of a storage system having a persistent reply cache, the method comprising: retrieving primary file system data structures from one or more storage devices into a memory of the storage system to enable retrieval of persistent reply cache information stored on a storage device; retrieving on-disk bin and bucket structures of a persistent reply cache file from the storage device into the memory; adding each on-disk bin structure to an initially empty set of in-core bin structures in the memory; for each in-core bin structure, retrieving an array of on-disk bucket structures from the storage device; adding each on-disk bucket structure of the array to an initially empty set of in-core bucket structures for the in-core bin structure; and processing enhanced non-volatile log (NVLOG) records stored in an NVLOG of the storage system using the in-core and on-disk structures.
