Task: Set I/O Scheduler For A Hard Disk To set a specific scheduler, simply type the command as follows: # echo {SCHEDULER-NAME} > /sys/block/{DEVICE-NAME}/queue/scheduler For example, set noop scheduler, enter: # echo noop > /sys/block/hda/queue/scheduler...
How to turn on thenoopscheduler for a device? How to turn on thenonescheduler for a device? What are the tunables fornoopornoneschedulers and what do they do? How does the logic within the scheduler work in choosing which I/O to dispatch next?
This is a config file. You point the scheduler at it via the--config=/etc/kubernetes/scheduler-config.yamlarg. You do NOT apply it to the cluster. K3s does not run the scheduler in a pod, and does not store anything in/etc/kubernetes/manifests, so following instructions to modify pod ...
第三种 CFQ(Completely Fair Scheduler),也被称为完全公平调度器,是现在很多发行版的默认 I/O 调度器,它为每个进程维护了一个 I/O 调度队列,并按照时间片来均匀分布每个进程的 I/O 请求。类似于进程 CPU 调度,CFQ 还支持进程 I/O 的优先级调度,所以它适用于运行大量进程的系统,像是桌面环境、多媒体应用等。
