CONTROLLING FILLING LEVELS OF STORAGE POOLS

摘要

Method, system, and computer program product embodiments of controlling filling levels of a plurality of storage pools are provided. A plurality of files is selected from each storage pool of the plurality of storage pools. Each file is then copied to a server and a list is updated. The list comprises an entry for each file of the plurality of files. Each entry comprises a status information. The status information indicates that the corresponding file has been copied to the server. Each entry further comprises an identifier indicating the storage pool on which the corresponding file is stored. If it is detected that the filling level of a storage pool reaches a predefined first threshold value, then a first set of files is determined by use of the list. Each file of the first set of files is replaced by a stub file. The status information is updated.

1. A method for controlling filling levels of a plurality of storage pools, each storage pool comprising a plurality of files, using a processor device in a computing system including a first computing device storing the plurality of storage pools, a second computing device in communication with the first storage device and storing a list including size information corresponding to each storage pool and to each file in each storage pool, and a server in communication with the first computing device and the second computing device, said method comprising:
providing a first threshold value for each respective storage pool representing a predefined maximum storage amount; monitoring an associated filling level of each respective storage pool as each file in each storage pool is copied to the server; if the filling level of a particular storage pool reaches a corresponding particular first threshold value, selecting a first set of files in the particular storage pool utilizing said list, the selected first set of files comprising an indication that each file in the selected first set of files is copied in the server; and replacing each file in the selected first set of files with a respective stub file for freeing storage space in the respective storage pool such that the associated filling level is less than the corresponding particular first threshold value and such that a new set of files may be stored therein.
