  • Patent number: 11226881
    Abstract: Techniques for managing a storage disk involve monitoring a duration of a fault of a faulted storage disk, wherein the faulted storage disk includes a first disk slice configured to store metadata and a second disk slice configured to store user data. The techniques further involve, in response to the duration reaching a first threshold value, replacing the first disk slice with a first available disk slice in a first non-faulted storage disk. The techniques further involve, in response to the duration reaching a second threshold value greater than the first threshold value, replacing the second disk slice with a second available disk slice in a second non-faulted storage disk. Accordingly, fault monitoring windows with different lengths are applied to disk slices for different logical tiers in the faulted storage disk. In this way, the reliability of data of a metadata tier can be effectively improved.
