Abstract
Techniques manage a redundant array of independent disks. In such a technique, an instruction to expand the RAID is received, the RAID being formed by a first group of storage devices and including a first group of RAID extents. A second group of RAID extents created on a second group of storage devices and logical units are created on the second group of RAID extents. In response to receiving an indication for a failure of the creation of the second group of RAID extents or the logical units, a notification is generated for indicating a failure of the expansion of the RAID without triggering a shuffling operation, the shuffling operation causing storage extents in the first and second groups of RAID extents to be distributed in the first and second groups of storage devices.
