0x00 前言
接到一个需求，有200台云主机系统盘扩容到了80g，/dev/sda已经变成了80g，需要对dev/sda1扩展分区大小。
0x01 编写主机清单
myluzh@myluzhMacBookPro % cat inventory
[node]
36.134.92.10
36.212.225.133
36.212.225.129
36.212.225.222
....
# 给node这个组设置账号密码
[node:vars]
ansible_ssh_port=22
ansible_ssh_user=root
ansible_ssh_pass="k@s8#as0912e"
# ansible_python_interpreter=/usr/bin/python3.10
0x02 编写playbook
myluzh@myluzhMacBookPro % cat playbook.yml
- name: 批量扩容磁盘
hosts: all
max_fail_percentage: 0
become: yes
tasks:
- name: 获取/dev/sda大小
shell: lsblk /dev/sda | awk 'NR==2 {print $4}' | tr -d 'G'
register: sda_size
- name: 获取未扩容之前的/dev/sda1大小
shell: lsblk /dev/sda1 | awk 'NR==2 {print $4}' | tr -d 'G'
register: sda1_size_before
- name: 扩展分区大小
command: growpart /dev/sda 1
when: sda_size.stdout|int >= 80 and sda1_size_before.stdout|int < sda_size.stdout|int
- name: 调整文件系统大小
command: resize2fs /dev/sda1
when: sda_size.stdout|int >= 80 and sda1_size_before.stdout|int < sda_size.stdout|int
- name: 获取扩容后的/dev/sda1大小
shell: lsblk /dev/sda1 | awk 'NR==2 {print $4}' | tr -d 'G'
register: sda1_size_after
- name: 检查扩容是否成功
assert:
that:
- sda_size.stdout|int >= 80
- sda1_size_after.stdout|int >= sda_size.stdout|int
0x03 执行playbook
-f 20就是并发20.
myluzh@myluzhMacBookPro % ansible-playbook -i inventory playbook.yml -f 20
