Problems solved by technology

[0003] LMT can provide some statistics of file system IO traffic, usage rate and other information, but it cannot analyze and alarm the system operating environment, Luster logs and other information, which does not play a big role in the operation and maintenance of Luster file system
When the Luster file system fails, it still takes a long time to analyze and locate the problem. If the administrator is not on site, it is difficult to find and solve the fault in time

Embodiment Construction

[0043] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0044] The Luster proposed in this embodiment has several factors that affect the stable and efficient operation of Luster: 1) the cluster system environment, such as network communication quality, time synchronization, etc., and 2) Luster's own bugs. 3) Other problems, such as exceeding the scope of use, etc.

[0045] The system operating environment and Luster operating status can be obtained through some testing tools and log information scanning and analysis. Therefore, scanning the system operating environment and log scanning, analyzing and alerting, and performing preliminary processing is to ensure the security and stability of the large-scale Luster parallel file system. feasible way to operate.

[0046] The main idea of ​​this embodiment is to periodically scan the system network quality, Luster log informatio...

Abstract

The invention discloses a failure alarm method and system for a Lustre parallel file system. The alarm method comprises the steps that (1) a monitor module periodically scans an OSS (Open Source Software) log; (2) the log information is analyzed to judge whether failure information is included, and then an alarm report for the failure information is created; (3) whether failures in the alarm report are serious is judged, and a separate report for serious failures is created for further analysis by a program; and finally the serious failure information and common alarm information are collected to be written in a txt document which is transmitted to an administrator through a mail hub. The failure alarm system of the invention comprises a LAToolkit service terminal, a storage client cluster, a main server cluster and a LAToolkit client. Intelligent failure analysis is achieved through the control of the system disclosed by the invention, a concise report is created, the approximate situations of the failures can be known remotely through a mobile phone, the detection time is saved, the cost of the method and the system is low, and just using the original equipment instead of adding new equipment can achieve the purpose.

Description

technical field [0001] The invention relates to the field of computers, in particular to a Luster parallel file system error alarm method and system thereof. Background technique [0002] The general environment of large-scale supercomputing centers is relatively complex. When the Luster parallel file system fails, there are many related factors. It usually takes a lot of time to locate the problem by manually searching logs and other information, and the fault cannot be resolved in time. . Currently, Luster's monitoring software mainly uses LMT. LMT can better present the historical usage status of Luster through some statistical information interfaces of Luster, such as the current read and write rate, space usage, and so on. [0003] LMT can provide some statistics on file system IO traffic, usage rate and other information, but it cannot analyze and alarm the system operating environment, Luster logs and other information, and it does not play a big role in the operati...
