Abstract
Dynamic provisioning of available space in a data storage system without having to configure partitions at system startup is presented. A system table may be maintained with entries corresponding to provisions within the available physical capacity of a data storage system. A volume table may be maintained that includes entries corresponding to territories within a logical data storage volume. When a data write operation is requested, a determination may be made as to whether physical space has been allocated for the territory in the volume that is to be written. If physical space has not yet been allocated, the necessary physical space may be allocated for the territory within the logical volume that is to receive the written data and the requested write operation may be performed. Metadata can be written to disk as to simplify recover from system crashes and unclean shutdowns.
