+## 设置磁盘调度算法
+本节介绍如何设置磁盘调度算法。LTS-20.03版本默认调度算法为bfq。
+
+
+
+### 临时修改调度策略
+
+例如将所有IO调度算法修改为mq-deadline，此修改重启后会失效。
+```
+echo mq-deadline > /sys/block/sd*/queue/scheduler
+```
+
+### 永久设置调度策略
+
+当systemd版本为systemd-243-27.oe1之前的版本，想要永久修改IO调度策略，可以修改/lib/udev/rules.d/60-block-scheduler.rules规则，将ATTR{queue/scheduler}="bfq"改为
+ATTR{queue/scheduler}="mq-deadline"，重启后生效。
+```
+# do not edit this file, it will be overwritten on update
+
+ACTION=="add", SUBSYSTEM=="block", \
+  KERNEL=="mmcblk*[0-9]|msblk*[0-9]|mspblk*[0-9]|sd*[!0-9]|sr*", \
+  ATTR{queue/scheduler}="mq-deadline"
+```
+
+当systemd版本为systemd-243-27.oe1以及之后的版本，可以通过在内核启动配置文件grub.cfg中的kernel行追加：elevator=mq-deadline，重启后生效。
+```
+linux   /vmlinuz-4.19.90-2003.4.0.0036.oe1.x86_64 root=/dev/mapper/openeuler-root ro resume=/dev/mapper/openeuler-swap rd.lvm.lv=openeuler/root rd.lvm.lv=openeuler/swap quiet crashkernel=512M elevator=mq-deadline
