In a networked printing environment having at least a number of workstations of users, a management unit maintains logic storage spaces in a memory, each allocated to a respective user. Digital data files sent from a user's workstation for printing contain an identification of the relevant user and are either of a first type or of a second type. The first type is formed by files which must be printed automatically, and the second type is formed by files which must be stored in the logic storage space of the user in the memory and may be printed only on a command from the operator control unit, which command identifies the relevant file. When handling a print job, the management unit checks, whether the job can be performed completely. If this appears not to be the case, the management unit converts the file into a file of the second type and, if necessary, creates a logic storage space for the relevant user and stores the file in the logic storage space of the relevant user. The same techniques are also used for scan and copy jobs. As a result, the file is not lost but remains available. On a command from the apparatus operator control panel, it can be retrieved and the job resumed.

A data storage system includes methods and apparatus that provide volumes for access by host computing devices. The volumes can have a storage size that is independently configurable from an actual amount of data storage that may or may not be associated with the volume. The volumes also have a persistent identifier. The volumes can have any amount of associated storage space allocated to the volume, including none, within the data storage system. Since the storage size and associated storage space are each independently configurable from each other, host that interface with the data storage system can perceive the volumes as being larger than they really are. A dynamic volume configuration technique is provided which allows storage space within storage devices in the data storage system to be dynamically associated and disassociated (i.e., added and removed) from the volumes on an as-needed basis, without requiring disruption of host activities with respect to the volumes. The persistent identifier of a volume allows all hosts and other data storage systems to “see” the volume. This allows a volume in one data storage system to have associated storage space from another volume in another data storage system. Using these techniques, the invention allows software applications and operating systems on hosts that interface to the data storage system to perceive that a volume is always present on the data storage system, even if storage space understood to be associated with the volume from the host's perspective is allocated elsewhere or is non-existent.

The invention provides a space distribution and management method and device for a network storage system, which are used for performing resource management operation in the network storage system. The device comprises a resource management unit, a forward space management unit and a backward space management unit, wherein the resource management unit is used for establishing a RAID (Redundant Array of Inexpensive Disk), dividing available space of the RAID into a plurality of resource blocks according to specified length and establishing a block list; an index area is established for logic resources when the logic resources are established; all index initial values pointing at physical resource blocks in the index area are null; the forward space management unit is used for enabling distribution of the actual physical resource blocks when processing an IO (Input Output) request on the logical resources; and the backward space management unit is used for recovering and utilizing idle resource blocks. In the method and the device, the utilization efficiency of storage space is effectively improved through distribution and recovery of the resource blocks.

The embodiment of the invention provides a storage space data processing method and device for a distributed file system, and the method comprises: carrying out the use information prediction according to the change rate of the storage space use information of a target storage volume in a set time period, and obtaining the storage space use information prediction data; and executing a corresponding storage space allocation operation on the target storage volume according to a comparison result of the storage space use information prediction data and a preset use threshold. According to the method and the device, the use condition of the storage space in the distributed file system can be accurately predicted, the corresponding storage space scheduling operation is timely and reliably executed, the large file writing failure condition is avoided, and the stable operation of the system is ensured.
