Problems solved by technology

[0007] The usual processing method is manual intervention throughout the process, and there is no reliable way to judge temporary offline disk failures, and they are all considered permanent disk failures, and all data on the disk needs to be rebuilt

Embodiment Construction

[0024] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0026] Step S100: In the Linux system, it is detected that a disk is offline. At this time, the offline event is generally regarded as a disk failure in the prior art. However, in reality, in many cases, the disk is not offline due to a disk failure, but only a temporary temporary offline phenomenon of the disk. Therefore, a certain "grace period" should be provided for the disk offline event, and the specific steps are as described in step S102.

Abstract

The invention discloses a magnetic disk off-line processing method in a Linux system. The magnetic disk off-line processing method includes the steps of sensing a magnetic disk in an offline state through the Linux system and canceling the magnetic disk from a storage system if the magnetic disk is not back online within a predetermined time. The magnetic disk off-line processing method in the Linux system can actively manage online and offline events of the magnetic disk, and reduce manual interventions. An administrator just needs to insert the magnetic disk in or pull the magnetic disk out according to prompts, and other work can be actively completed by the system. Temporary faults are not actively processed in an extended period so as to prevent date reconstruction from causing extra input and output (IO) pressure.

Description

technical field [0001] The present invention basically relates to the server field, and more specifically, relates to a disk offline processing method in a Linux system. Background technique [0002] Carnegie Mellon University pointed out at the 5th USENIX Conference in San Francisco that the conclusion after researching about 100,000 disks is that the actual failure probability of disk products is 15 times that of the MTTF (mean time to failure) index many. The actual annual probability of failure generally exceeds 1%, usually around 2-4%. In some extreme cases, even as high as 13%, or even 24%. And MTTF is only 0.88% in the worst case. [0003] According to statistics from the International Data Corporation (IDC), the global data generation reached 1.8ZB in 2011. It is predicted that in the next ten years, the total number of global servers used to store data will increase tenfold. By 2015, nearly 20% of all information will be stored in cloud storage services. [00...
