2.3. Receive Flow Steering을 사용하여 네트워크 성능 향상

절차

1. 다음 MCO 샘플 프로필을 YAML 파일에 복사합니다. 예를 들어 enable-rfs.yaml 은 다음과 같습니다.

   apiVersion: machineconfiguration.openshift.io/v1
   kind: MachineConfig
   metadata:
     labels:
       machineconfiguration.openshift.io/role: worker
     name: 50-enable-rfs
   spec:
     config:
       ignition:
         version: 2.2.0
       storage:
         files:
         - contents:
             source: data:text/plain;charset=US-ASCII,%23%20turn%20on%20Receive%20Flow%20Steering%20%28RFS%29%20for%20all%20network%20interfaces%0ASUBSYSTEM%3D%3D%22net%22%2C%20ACTION%3D%3D%22add%22%2C%20RUN%7Bprogram%7D%2B%3D%22/bin/bash%20-c%20%27for%20x%20in%20/sys/%24DEVPATH/queues/rx-%2A%3B%20do%20echo%208192%20%3E%20%24x/rps_flow_cnt%3B%20%20done%27%22%0A

           filesystem: root
           mode: 0644
           path: /etc/sysctl.d/95-enable-rps.conf

2. MCO 프로필을 생성합니다.

   $ oc create -f enable-rfs.yaml

3. 50-enable-rfs 항목이 나열되었는지 확인합니다.

   $ oc get mc

4. 비활성화하려면 다음을 입력합니다.

   $ oc delete mc 50-enable-rfs
