Abstract

The invention discloses a magnetic disc fault handling method and device. The method comprises the steps of monitoring each magnetic disc in a magnetic disc array in real time, and acquiring fault information of a failure magnetic disc when a fault is detected to occur in an arbitrary magnetic disc; and acquiring a current state of the magnetic disc array, judging whether the arbitrary magnetic disc is allowed to be removed by the magnetic disc array according to the current state, if yes, removing the failure magnetic disk, otherwise continuing to use the failure magnetic disc and restoring the fault of the fault magnetic disc according to the fault information. When the failure magnetic disc is monitored, the failure magnetic disc is not directly removed, while the failure magnetic disc is removed when the current state of the magnetic disc array is determined to allow removal of a magnetic disc, thus, the magnetic disc is prevented from being directly removed when the current state of the magnetic disc array is not allowed to remove the magnetic disc, the risk of data loss caused by collapse of the whole magnetic disc array is greatly reduced, and the data reliability is ensured.

Description

technical field [0001] The present invention relates to the technical field of high availability of storage devices, and more specifically, relates to a disk failure processing method and device. Background technique [0002] In traditional storage devices, after a disk included in RAID (disk array) reports a failure, the disk will be removed from the disk array, but this method leads to the risk of catastrophic data loss. For example, commonly used RAID 5, RAID 5 only allows one of its contained disks to fail and be removed, but if a second disk fails and is removed, the entire RAID 5 will collapse. Adding a new disk can cause catastrophic data loss to the storage device. [0003] To sum up, in the technical solutions for dealing with disk failures in the prior art, there is a problem that catastrophic data loss of corresponding storage devices may be caused by removal of disks. Contents of the invention [0004] The purpose of the present invention is to provide a disk...
