Abstract

The invention discloses an RAID read-write timeout processing method, which comprises the following steps: if a first disk of which the read speed exceeds a first preset duration exists in the RAID, reading data of the first disk by utilizing a check block of the RAID; if a second disk of which the writing speed exceeds a second preset duration exists and the block type of the second disk is a data block, updating the RAID by using the verification block; if a third disk with the writing speed exceeding a third preset duration exists and the block type where the third disk is located is a verification block, detecting the RAID; if the redundancy of the RAID is complete and the RAID has a hot standby space, removing the third disk from the RAID, and updating the RAID by using the verification block; and if the redundancy of the RAID is incomplete and/or the RAID does not have the hot standby space, reserving the third disk, and controlling the RAID to be offline. By means of the method, the reliability of the RAID in the using process can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a RAID read / write timeout processing method, device, equipment and medium. Background technique [0002] Because the parity block in the RAID (Redundant Arrays of Independent Disks, disk array) can provide it with redundant protection, so the reliability and stability of the RAID during use are guaranteed. [0003] A RAID with a verification function will encounter the problem of disk read and write timeouts. If there are disks with a slow read and write speed in the RAID, it will affect the response speed of the entire RAID to the system. In the prior art, in order to avoid the occurrence of the above situation, disks with too slow read and write speeds are generally removed from the RAID. However, this operation mode will cause the RAID to lose its redundancy function, which will greatly reduce the reliability of the RAID during use. Currently, there is no effective solutio...
