Abstract
An apparatus comprises a processing device configured to identify faults associated with a logical address space in a fault domain of a storage system, the faults specifying fault reason codes and metadata types for logical pages in the logical address space associated with the faults. The processing device is also configured to determine a fault summary characterizing impact of the faults in the fault domain of the storage system, the fault summary being based on aggregating fault scores assigned to the fault reason codes and the metadata types specified in the faults. The processing device is further configured to generate a recommendation on whether to initiate recovery of the fault domain of the storage system based on the fault summary, and to initiate recovery of the fault domain of the storage system based on the generated recommendation.
