Abstract
Embodiments of the present invention enable dynamic repartitioning of data storage in response to one or more triggers. In embodiments, a trigger may be a user-initiated action, a system-generated action, and/or an inference based on storage usage parameters. Applications of the present invention are its use in embodiments of a storage management system comprising a file system manager and a volume manager, where the placement of data into a partition (data storage region) may be specified by matching one or more disk region placement data attributes assigned to data with corresponding disk region attributes. In embodiments, dynamic repartitioning comprises adjustment of the location of the boundary between adjacent disk partitions and, if necessary, rebalancing of the data stored within the partitions by identifying mismatched data and relocating it to the partition with which it is associated.
