RHCE8练习题18: parted创建和使用分区
创建一个名为 /home/student/ansible/partion.yml 的playbook 它将在 所有 受管节点上创建分区：
- 在 vdb 分区上创建一个 1500M 的主分区，分区号 1 ，格式化为 ext4 , dev组中主机 将分区 永久 挂载到 /data
- 如果磁盘空间不足，给出提示信息，Could not create partiontion of that size , 并创建 800M 分区
- 如果vdb不存在，给出提示信息， This disk is not exist
提示：
模块 block rescue ，parted ，file ，filesystem , mount , debug
Answer：
vim /home/student/ansible/partion.yml---
- name: create and use parted
hosts: all
tasks:
- name: create parted
block:
- name: create 1500M partition
parted:
device: /dev/vdb
number: 1
state: present
part_end: 1500MiB
- name: format fs
filesystem:
fstype: ext4
dev: /dev/vdb1
- name:
block:
- name: create directory
file:
path: /data
state: directory
- name: mount
mount:
src: /dev/vdb1
path: /data
state: mounted
fstype: ext4
when: inventory_hostname in groups.dev
rescue:
- name: errors
debug:
msg: "Could not create partition of that size"
- name: create 800M partition
parted:
device: /dev/vdb
number: 1
state: present
part_end: 800MiB
when: ansible_devices.vdb is defined
- name: "error"
debug:
msg: "this disk is not exist"
when: ansible_devices.vdb is not defined验证:
ansible all -a 'lsblk'
ansible dev -a 'cat /etc/fstab'
