是否使用 direct io，测试过程不使用OS 自带的buffer，使测试磁盘的结果更真实。Linux读写的时候，内核维护了缓存，数据先写到缓存，后面在后台写到SSD。读的时候也优先读缓存里的数据。这样速度可以加快，但是一旦掉电，缓存里的数据就没有了。所以有一种模式叫做direct io，跳过缓存，直接读写SSD。
If this option is false, then fio will error out if the files it needs to use don't already exist. Default: true. allow_mounted_write=bool If this isn't set, fio will abort jobs that are destructive (eg that write) to what appears to be a mounted device or partition. This ...
But this command results into an error "Invalid argument". If i change the parameter --direct=0, I'm able to issue the command successfully. Can you help me to understand, why with direct=1, the fio command results in an error ?
Fio will normally perform I/Os until it has exhausted the size of the region set by size, or if it exhaust the allocated time (or hits an error condition). With this setting, the range/size can be set independently of the number of I/Os to perform. When fio reaches this number, it...
