Method and apparatus for managing storage system
Techniques for managing a storage system involve: in response to a storage device in a group of storage devices failing, determining multiple stripes in the storage system which are associated with the failed storage device; selecting a first storage device and a second storage device from the group of storage devices respectively, the first storage device and the second storage device being a first candidate and a second candidate of storage devices for rebuilding a first stripe and a second stripe among the multiple stripes to form a first rebuilt stripe and a second rebuilt stripe respectively; obtaining a coupling degree between the first rebuilt stripe and the second rebuilt stripe, the coupling degree describing a conflict degree of rebuilding the first stripe and the second stripe in parallel; and identifying the first candidate and the second candidate on the basis of the obtained coupling degree.
