SYSTEMS AND METHODS FOR MANAGING FILES ON A STORAGE DEVICE

摘要

Described herein are techniques for the dynamic allocation of storage capacity between multiple namespaces associated with a storage system. Data from multiple namespaces (301, 302, 303, 304) is stored in a common pool of addresses of the storage system (902) and data from each namespace is capable of being written to any free address of the storage system at any time (1002). Metadata associated with each of the files stored in the storage system is maintained that tracks the particular storage address or addresses and namespace associated with the file. Storage capacity can be dynamically allocated between multiple namespaces (912) by writing data to free blocks (116A) and updating the metadata accordingly.
