RHCE之路--08创建和使用分区

RHCE之路–08创建和使用分区

1. 考题

创建一个名为 /home/student/ansible/partition.yml 的 playbook ，它将在所有受管节点上创建分区：

1. 在vdb 创建一个1500M 主分区，分区号1 ，并格式化ext4
2. dev 组将分区永久挂载到/data如果磁盘空间不够，
3. 给出提示信息Could not create partition of that size
4. 创建800MiB 分区
5. 如果 vdb不存在，则给出提示信息this disk is not exist

2. 解题

2.1 编辑yml

vi /home/student/ansible/partition.yml

---
- hosts: all

  tasks:
    - block:
        - name: create 1500M
          parted:
            device: /dev/vdb
            number: 1
            state: present
            part_end: 1500MiB
          when: ansible_devices.vdb is defined
      rescue:
        - name: not enough 1500m
          debug:
            msg: "Could not create partition of that size"
          when: ansible_devices.vdb is defined
        - name: create 800m
          parted:
            device: /dev/vdb
            number: 1
            state: present
            part_end: 800MiB
          when: ansible_devices.vdb is defined
      always:
        - name: format
          filesystem:
            fstype: ext4
            dev: /dev/vdb1
          when: ansible_devices.vdb is defined
        - name: mkdir
          file:
            state: directory
            path: /data
          when: ansible_devices.vdb is defined
        - name: mount disk
          mount:
            path: /data
            src: /dev/vdb1
            fstype: ext4
            state: mounted
          when: ansible_devices.vdb is defined
        - name: vdb is not defined
          debug:
            msg: "this disk is not exist"
          when: ansible_devices.vdb is not defined

2.2 执行yml

ansible-playbook /home/student/ansible/partition.yml

3. 确认本题是否成功

没有错误提示

ansible all -a 'lvs'
