Title: Preallocated disk queuing

Abstract: A method, system and computer program product for managing preallocated disk space are presented. The method includes placing a plurality of requests for preallocated disk space on a disk space request queue, wherein each preallocated disk space is preallocated for a fixed amount of disk space and a fixed length of time, and wherein an application using an issued preallocated disk space for more than the fixed length of time results in the application being barred from further current use of the issued preallocated disk space. The requests are sorted in the disk space request queue according to a priority algorithm that establishes a priority level for each of the requests, and preallocated disk space is allocated to requesters according to the priority level established by the priority algorithm.
