Abstract: A computer-implemented method, according to one embodiment, includes: receiving configuration information which corresponds to hardware and software configurations of a user computing environment. This configuration information is used to create a test computing environment which emulates the hardware and software configurations of the user computing environment. Moreover, a software update is applied to the test computing environment, and the test computing environment is operated with the software update applied thereto. Results which correspond to performance of the test computing environment during the operation are received, and a determination is made as to whether one or more errors were experienced by the test computing environment during the operation. In response to determining that at least one error was experienced by the test computing environment during the operation, implementation of the software update in the user computing environment is postponed.

Abstract: The method includes identifying, by one or more computer processors, a grouping of elements in a storage system. The method further includes identifying, by one or more computer processors, a first element from the identified grouping of elements. The method further includes identifying, by one or more computer processors, a root unit of the first element from the identified grouping of elements. The method further includes determining, by one or more computer processors, a past usage history of computer resources for the identified root unit of the first element. The method further includes calculating, by one or more computer processors, a future usage of computer resources for the identified root unit based upon the determined past usage history.

Abstract: A computational device maintains logical mirroring of a first file system with a second file system. A first set of input/output (I/O) requests is satisfied from the first file system while the second file system is undergoing defragmentation. A second set of I/O requests is satisfied from the second file system while the first file system is undergoing defragmentation.
