Problems solved by technology

At this time, the next IO operation will be executed after the completion of one IO operation. However, if any IO operation hangs up during the processing of any IO operation and cannot be identified, it may continue to wait for the hangup. The IO operation cannot perform subsequent IO operations, thereby reducing the efficiency of the overall IO operation

Abstract

The present invention provides an IO hanging identification method, comprising: obtaining target IO; identifying whether the target IO and the previous IO of the target IO are continuous IO; Calculate the target processing time of the target IO; determine the timeout period of the target IO according to the target processing time of the target IO; if the actual processing time of the target IO reaches the timeout period of the target IO, identify the target IO as a hang state. The invention also discloses an IO hanging identification device, a computer device and a computer-readable storage medium. The present invention can identify whether the IO hangs up, thereby reducing the waiting time when the IO hangs.

Description

technical field [0001] The present invention relates to the field of storage technology, in particular to a method, device, computer device and storage medium for identifying an IO hang-up. Background technique [0002] Computer read and write operations are also called IO operations, and IO is input / output. Specifically, an IO operation may be a read IO operation (for example, reading data from a disk to a memory) or a write IO operation (for example, writing data into a disk). [0003] Usually, continuous read IO operations or continuous write IO operations are performed in the computer, or data read by the read IO operations are returned to target parameters. At this time, the next IO operation will be executed after the completion of one IO operation. However, if any IO operation hangs up during the processing of any IO operation and cannot be identified, it may continue to wait for the hangup. The IO operation cannot be performed, and subsequent IO operations cannot b...
