System fault handling method and apparatus, device, and storage medium

An electronic device, comprising:

• a memory, configured for storing computer programs;
• and a processor, configured for executing the computer programs, wherein the processor, upon execution of the program instructions, is configured to:
• divide disks in a redundant array of independent disks (RAID) based on a number of stripes, to enable blocks with a same number as the disks to exist on each stripe, then configure multi-state standby blocks for the stripes, and distribute the multi-state standby blocks on the disks in the RAID, so as to enable the disks to use the multi-state standby blocks to run at a same time to handle faults when the faults occur at the same time;
• acquire fault information factors corresponding to fault blocks after the faults occur on the blocks, and then store the fault information factors in stripe block state mapping items in a stripe block state mapping linked list;
• and
• select corresponding handling strategies based on different stripe block state mapping items, so as to perform fault handling operations on the fault blocks corresponding to the stripe block state mapping items by using the handling strategies;
• wherein before the selecting corresponding handling strategies based on different stripe block state mapping items, so as to perform fault handling operations on the fault blocks corresponding to the stripe block state mapping items by using the handling strategies:
• set a timing program for the stripe block state mapping linked list, so as to perform the corresponding fault handling operations on the stripe block state mapping items according to a preset time period.

A non-transitory computer-readable storage medium, being configured for storing computer programs, wherein upon execution by a processor, the computer programs are configured to cause the processor to:

• divide disks in a redundant array of independent disks (RAID) based on a number of stripes, to enable blocks with a same number as the disks to exist on each stripe, then configure multi-state standby blocks for the stripes, and distribute the multi-state standby blocks on the disks in the RAID, so as to enable the disks to use the multi-state standby blocks to run at a same time to handle faults when the faults occur at the same time;
• acquire fault information factors corresponding to fault blocks after the faults occur on the blocks, and then store the fault information factors in stripe block state mapping items in a stripe block state mapping linked list;
• and
• select corresponding handling strategies based on different stripe block state mapping items, so as to perform fault handling operations on the fault blocks corresponding to the stripe block state mapping items by using the handling strategies;
