Abstract
A method, article of manufacture, and apparatus for maintaining a cache index inside a deduplicated storage system is discussed. A determination is made to flush a cache buffer to the cache index, wherein both the cache buffer and the cache index comprise a plurality of cache buckets, wherein the cache buckets are stored on a plurality of logical data blocks. A write is initiated to at least one of the plurality of logical data blocks, wherein the write comprises at least one of the cache buckets. An error is received in response to the write request. The error is stored in a memory on the deduplicated storage system.
