Abstract
A method for removing a mass storage system from a composite computer system. The composite computer system comprises a multiplicity of mass storage systems which respectively provide at least one file system for storing data, at least one component computer for carrying out one or more processes, a network which connects the multiplicity of mass storage systems to the at least one component computer and an access controller which controls access by the processes to the file systems which have been provided. A mass storage system to be removed is first of all selected. All of the file systems provided by the selected mass storage system are then marked. The marked file systems are released by copying data and diverting access by processes to the copied data from the marked file system to at least one file system which has not been marked. After the releasing operation has been concluded, it is signaled that the selected mass storage system can be removed from the composite computer system.
