A storage system, a file system and a data management method using a non-volatile random access memory and a storage device are provided to shorten the mount time of a file system and improve the performance. A first storage(501) keeps file meta data and file data, and a second storage(502) keeps an in-memory data and the page meta data of the first storage. When mounting the file system, a storage system(500) provides the page meta data or some of in-memory data stored in the second storage to the file system. Base on the offset information of the first storage, the page meta data are stored in the second storage by the file system. |
