Dynamically updating metadata

A metadata updating system for dynamically updating metadata associated with a file system, the metadata updating system comprising:

• a processor;
• a creation module coupled to the processor to,
• create a shadow data block corresponding to a metadata storage of the file system, the metadata storage storing metadata files associated with the file system;
• and
• create a shadow file system metadata (FSM) index map in the shadow block data;
• an association module to associate the shadow FSM index map with the metadata storage through an index map of the metadata storage, the index map being indicative of a location of the metadata files in the metadata storage;
• and
• an updating module to update the shadow data block to add a metadata file in the metadata storage to update the metadata.

A non-transitory computer-readable medium comprising instructions executable by a processing resource to:

• create a shadow file system metadata (FSM) index map in a shadow data block, the shadow data block associated with a metadata storage of the file system and the metadata storage storing metadata files associated with the file system;
• associate the shadow FSM index map 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;
• and
• modify the shadow FSM index map to dynamically add a metadata file to the file system to dynamically update the metadata storage for updating the metadata.
