This article mainly introduces "what impact does GlusterFS space usage have on performance". In daily operation, I believe many people have doubts about what impact GlusterFS space usage has on performance. Xiaobian consulted all kinds of information and sorted out simple and easy operation methods. I hope to help you answer the question of "what impact GlusterFS space usage has on performance"! Next, please follow the small series to learn together!

As with all file systems, GlusterFS file system performance starts to degrade with excessive space usage, typically when space usage is greater than 90% of total capacity (empirical value, from GlusterFS mailing list), performance starts to degrade severely, typically dropping to 50% or less of previous performance.

In a real-world production environment, it is recommended to keep available capacity above 20%, start warning below 20% and start increasing available space, and severely warn below 10% when it is too late to remedy.

At this point, the study of "What effect does GlusterFS space usage have on performance" is over, hoping to solve everyone's doubts. Theory and practice can better match to help everyone learn, go and try it! If you want to continue learning more relevant knowledge, please continue to pay attention to the website, Xiaobian will continue to strive to bring more practical articles for everyone!
