Embodiment 1

[0024] The embodiment of the present invention provides a detection method, such as figure 1 Said, said method comprises:

[0025] Step 11: Detect and analyze the recorded data of each storage unit in the storage system in response to the read and write operations, and obtain the read and write characteristic parameters of the storage unit;

[0026] Step 12: Predict the idle time based on the read-write characteristic parameters of the storage unit;

[0027] Step 13: Monitor the read and write operations of the storage unit in the storage system during the first period of the idle time, and obtain a first monitoring result;

[0028] Step 14: If the first monitoring result indicates that there is no read / write operation on the storage unit in the storage system within the first period of time, then generate a first operation instruction;

[0029] Step 15: According to the first operation instruction, detect the storage unit in the storage system during the second period of th...

Embodiment 2

[0045] The embodiment of the present invention provides a detection method, such as image 3 Said, said method comprises:

[0046] Step 31: Detect and analyze the recorded data of each storage unit in the storage system in response to the read and write operations, and obtain the read and write characteristic parameters of the storage unit;

[0047] Step 32: Predict the idle time based on the read-write characteristic parameters of the storage unit;

[0048] Step 33: Monitor the read and write operations of the storage unit in the storage system during the first period of the idle time, and obtain a first monitoring result;

[0049] Step 34: If the first monitoring result indicates that there is no read and write operation on the storage unit within the first time period, then monitor the read and write operations on the storage unit within a third time period to obtain the first 2. Monitoring results;

[0050] Step 35: If the second monitoring result indicates that there i...

Embodiment 3

[0084] The embodiment of the present invention provides a detection method, such as image 3 Said, said method comprises:

Abstract

The invention discloses a detection method and device. The method comprises the following steps: detecting and analyzing recording data of each storage unit in a storage system in response to a read-write operation to obtain read-write characteristic parameters of the storage unit; based on the read-write characteristic parameters of the storage unit, predicting an idle duration; monitoring the read-write operation of the storage unit in the storage system within a first time period of the idle duration to obtain a first monitoring result; if the monitoring result indicates that there is no read-write operation of the storage unit in the storage system within the first time period, generating a first operation instruction; detecting the storage unit in the storage system within a second time period of the idle duration according to the first operation instruction, and determining a detection result, wherein the second time period is at least a part of duration in the residual duration excluding the first time period in the idle duration.

Description

technical field [0001] The invention relates to hard disk detection technology in the field of information processing, in particular to a detection method and device. Background technique [0002] Distributed storage systems often use mechanical disks as storage devices. Such storage devices have a high probability of failure. At present, when solving the problem of storage devices, passive scanning is often adopted, that is, the storage device is directly connected to the storage system for use; A storage area in the disk triggers the detection mechanism; when a failure of the storage unit is detected, the number and location of bad sectors in the storage unit are recorded and a sector is reassigned for data migration and access. [0003] It can be seen that the detection operation of the storage unit provided by the above-mentioned prior art is a passive method, that is, the corresponding processing will be performed only after the detection determines that the storage u...
