Method, electronic device and computer program product for managing storage disk

An electronic device, comprising:

• a processor;
• and
• a memory coupled to the processor, wherein the memory has an instruction stored therein, the instruction, when executed by the processor, causes the device to execute actions, and the actions comprise:
• monitoring a duration of a fault of a faulted storage disk, wherein the faulted storage disk comprises a first disk slice configured to store metadata and a second disk slice configured to store user data;
• 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;
• and
• 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.

A computer program product having a non-transitory computer readable medium which stores a set of instructions to manage a storage disk;

• the set of instructions, when carried out by computerized circuitry, causing the computerized circuitry to perform a method of:
• monitoring a duration of a fault of a faulted storage disk, wherein the faulted storage disk comprises a first disk slice configured to store metadata and a second disk slice configured to store user data;
• 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;
• and
• 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.
