Abstract

The invention discloses a multi-path IO adjusting method and device. The method comprises the steps of detecting an IO rate of each link; judging whether each link is abnormal or not; carrying out statistic analysis on transmission data of the link with an abnormal IO rate to obtain an analysis result; and closing the link with the abnormal IO rate according to the analysis result. The device comprises a detection unit for detecting the IO rate of each link, a judgment unit for judging whether each link is abnormal or not, an analysis unit for carrying out statistic analysis on the transmission data of the link with the abnormal IO rate to obtain the analysis result, and a closing unit for closing the link with the abnormal IO rate according to the analysis result. According to the method and the device, the effect of hierarchical control of the IO rate can be achieved, the IO efficiency is improved by fully utilizing the link characteristics, and the condition that the IO rate is too low when a fault link is blocked.

Description

technical field [0001] The invention belongs to the technical field of Linux system process scheduling, and in particular relates to a multipath IO adjustment method and device. Background technique [0002] Servers in the prior art all use multipath multipath software for storage disaster recovery processing, but its load balancing degree is still insufficient, and it can only realize the situation that multiple paths share IO evenly, without considering whether the actual link meets the standard. When a path fails, the path will not be closed, resulting in a large amount of IO accumulation until the path fails, which shows that this greatly reduces the IO rate. Contents of the invention [0003] In order to solve the above problems, the present invention provides a multi-path IO adjustment method and device, which can achieve the effect of hierarchical control of IO rate, make full use of link characteristics, improve IO efficiency, and avoid the problem of too low IO sp...
