Abstract
Embodiments of the present disclosure provide method, device and computer program product for managing a storage system. The storage system includes a disk having a plurality of extents. The method comprises obtaining metadata associated with an RAID stripe in a first RAID of a first type, the first RAID including at least a part of extents from the plurality of extents. The method also comprises allocating an additional extent to the RAID stripe. The method further comprises converting, based on the allocated additional extent and by modifying the metadata, the first RAID of the first type into a second RAID of a second type in a degraded mode. Additionally, the method comprises initiating, based on the modified metadata, a rebuilding process for the second RAID, so as to convert the second RAID from the degraded mode to a normal mode.
