1. A method of accelerating recovery of a file system in a multi-tiered storage system, the multi-tiered storage system including a volatile cache memory, persistent fast storage and persistent disk storage, the persistent disk storage storing a set of metadata objects of the file system, the volatile cache memory temporarily storing a subset of the set of metadata objects of the file system, the method comprising: configuring the persistent fast storage to store the set of metadata objects stored on the persistent disk storage; disabling the subset of the set of metadata objects from being accessed via the volatile cache memory; updating inconsistent metadata objects of the set of metadata objects stored on the persistent fast storage during the recovery of the file system; and configuring the persistent disk storage to store the set of metadata objects of the file system stored on the persistent fast storage.
