Method for handling block errors on a deduplicated storage system

摘要

A method, article of manufacture, and apparatus for maintaining a cache index inside a deduplicated storage system is discussed. A block allocation is requested from a persistent storage device, wherein the block allocation comprises a logical block for storing data. The logical block is determined to be unavailable. A next sequential block is requested from the persistent storage until an available logical block is located, the available logical block satisfying the block allocation. Data comprising a plurality of buckets is written to the available logical block.
