Abstract
A system and method for providing a faster disk recovery is provided by bypassing the file system cache temporarily holding a sub set of metadata objects of the file system and instead using a persistent fast storage that can be accessed at deterministic speeds to hold all the metadata objects of the file system. The system speeds recovery by only writing updated metadata objects to the persistent disk storage when file system recovery is complete.
