5.2. 禁用 IRDMA 内核模块

流程

1. 运行以下命令生成以下机器配置文件：

   $ cat <<EOF > 99-machine-config-blacklist-irdma.yaml

   输出示例

   apiVersion: machineconfiguration.openshift.io/v1
   kind: MachineConfig
   metadata:
     labels:
       machineconfiguration.openshift.io/role: worker
     name: 99-worker-blacklist-irdma
   spec:
     kernelArguments:
       - "module_blacklist=irdma"

2. 运行以下命令，在集群中创建机器配置并等待节点重新引导：

   $ oc create -f 99-machine-config-blacklist-irdma.yaml

   输出示例

   machineconfig.machineconfiguration.openshift.io/99-worker-blacklist-irdma created

3. 运行以下命令，在每个节点上验证模块尚未加载的 debug pod:

   $ oc debug node/nvd-srv-32.nvidia.eng.rdu2.dc.redhat.com
   Starting pod/nvd-srv-32nvidiaengrdu2dcredhatcom-debug-btfj2 ...
   To use host binaries, run `chroot /host`
   Pod IP: 10.6.135.11
   If you don't see a command prompt, try pressing enter.
   sh-5.1# chroot /host
   sh-5.1# lsmod|grep irdma
   sh-5.1#
