一 简介 FIO是一款开源的 I/O 压力测试工具,主要是用来测试磁盘的IO性能。它可以支持多种不同的I/O引擎。...fio 官网地址:http://freshmeat.net/projects/fio/ fio文档:https://fio.readthedocs.io/en/latest/index.html 二 安装...zero_buffers 用0初始化系统buffer nrfiles=8 每个进程生成文件的数量 执行多次测试的时候 ,由于命令行参数过多影响...,不太直观,可以将参数写到配置文件中,把全局变量和测试变化的参数写在不同的块里,最后运行即可,比如我们要测试多个rw场景 write,readwrite ,可以写配置文件 fio_yace.cfg [...最后命令行运行 fio fio_yace.cfg 即执行测试。测试结果的数据较多,主要观察吞吐量和IOPS两个。当然延迟也需要进行观察。
前言 fio是一个适应性非常强的软件,基本上能够模拟所有的IO请求,是目前最全面的一款测试软件,之前在看德国电信的一篇分享的时候,里面就提到了,如果需要测试存储性能,尽量只用一款软件,这样从上层测试到底层去...,才能更好的去比较差别 fio对于ceph来说,可以测试文件系统,基于文件系统之上测试,可以测试内核rbd,将rbdmap到本地格式化以后进行测试,或者基于librbd直接对rbd进行测试,这个是目前都已经有的测试场景...,这些不在本篇的讨论的范围内,今天讲的是一种新的测试场景,直接对ceph的底层存储进行测试 ?...配置测试 下面需要准备两个配置文件,一个是ceph自身的,一个是fio配置文件,我们看下我的环境下这个配置文件如何写的 写fio的测试文件 vim filestore.fio [global] ioengine...,根据自己的需要对不同的存储设备和组合进行测试就可以了 总结 作为一个新的测试模型的出现,更加完善了ceph的整体体系,也给磁盘的选型增加更好的测试工具
