Linux上LVM快照数据一致性迁移

LVM Snapshot Data Consistency Migration on Linux

在基于Linux的生产系统中,人们越来越普遍地利用LVM的快照技术做数据一致性迁移和文档版本回溯,但是对于性能分析方面目前还没有相关论述文章。详细介绍LVM快照数据一致性迁移,着重分析迁移失真度以及由此带来的生产系统性能损耗,并通过实验证明性能损耗不会超过10%的结论。

For the production system based on Linux,people are more and more inclined to transport data consistently and recover former document edition through LVM snapshot technology.There is no paper on analyzing the performance of this aspect.Introduces LVM snapshot data consistency migration comprehensively,analyzes the migration distortion and the production system performance loss caused by migration.Experimental data proves the conclusion that the performance loss is less than 10 percent.
