为系统守护进程预留计算资源

Reserve Compute Resources for System Daemons  

为系统守护进程预留计算资源   

看了一下代码，CPU设置不对的话， 其实不用重新安装openness .

# git grep reserved_cpus

只给 reservedSystemCPUs  使用了。

https://kubernetes.io/zh/docs/tasks/administer-cluster/reserve-compute-resources/

 

EXPECTID=0

HT_SIBLINGS=`cat /sys/devices/system/cpu/cpu$EXPECTID/topology/thread_siblings_list`  # 0,8

CORE_SIBLINGS=`cat /sys/devices/system/cpu/cpu$EXPECTID/topology/core_siblings_list`  # 0-15

RESERVED=$HT_SIBLINGS

[[ ! $HT_SIBLINGS =~ "," ]] && RESERVED=${CORE_SIBLINGS//-/,}

sed -i -e 's/reservedSystemCPUs:.*/reservedSystemCPUs: '"$RESERVED"'/' /var/lib/kubelet/config.yaml

sed -i -e 's/reserved_cpus:.*/reserved_cpus: "'"$RESERVED"'"/' flavors/sdewan-hub/all.yml

systemctl status kubelet

systemctl restart kubelet

 

这样就可以了。
