ABSTRACT:
A method and an apparatus to perform fast log replay have been disclosed. In one embodiment, the method includes preloading a buffer with data based on a catalog in response to a failure of a storage server and replaying a log as the buffer is being preloaded, wherein replaying the log comprises re-executing a set of modifying operations previously logged in a local non-volatile storage device in the storage server using the data preloaded.
