Abstract
A method, system, computer system, and computer program product to allocate storage resources among multiple logical volumes. In response to a request to perform a set of operations on multiple logical volumes, a set of allocations of available storage space for performing the set of operations is made. At the time of identifying the storage regions to use for each allocation, the remaining operations and the storage regions that would be available for performing the remaining operations are examined. The rules for implementing each of the logical volumes can be evaluated as part of this examination. If it is apparent that one of the remaining operations will fail based upon a particular set of allocations, space allocated for a previous operation can be de-allocated and alternative allocations can be examined to find a set of allocations that enable the request to be performed successfully.
