三.将单块磁盘基于lvm管理创建多个挂载点并配置开机自动挂载

1.环境准备

3.测试验证

  1.执行剧本
(venv) root@JasonYin2020:~/nx_ops/ops-playbook# ansible-playbook -i  /root/nx_ops/kubespray-release-2.29/inventory/yinzhengjie-k8s/inventory.ini lvm_k8s_storage.yml

温馨提示:
  我上面的环境，GPU-POD01-09节点执行会报错，因为其nvme1n1被根分区占用，无法格式化使用，因此需要修改剧本，该对应的主机单独再执行一次即可。



  2.测试验证
(venv) root@JasonYin2020:~/nx_ops/ops-playbook#ansible -i  /root/nx_ops/kubespray-release-2.29/inventory/yinzhengjie-k8s/inventory.ini gpu -m shell -a 'df -h | grep data'
