Abstract: Dynamic updating of metadata associated with a file system is described herein. In accordance with an example, the updating includes creating a shadow file system metadata (FSM) index map in a shadow data block. The shadow data block is associated with a metadata storage of the file system and the metadata storage stores metadata files associated with the file system. The shadow FSM index map is associated with the metadata storage through an index map of the metadata storage, the index map being indicative of the metadata files in the metadata storage. The shadow FSM index map is updated to dynamically update the metadata associated with the file system, in the metadata storage.
