Ansiable-ploybook LVM

Ansible 配置文件修改

位置在：vim /etc/ansible/ansible.cfg

host_key_checking = False         # 首次连接是否需要检查key认证，建议设为False  

主机清单编写

[master]
192.168.1.80 ansible_connection=local    【可以本地执行】


[master:vars]
hostanme=master01

[client]
192.168.1.81hostname=node01
192.168.1.82 hostname=node02
[client:vars]
ansible_ssh_port=22
ansible_ssh_user=root
ansible_ssh_pass=123456

[redis:children]

编写vars_file

[root@master01 lvm]# vim storage_vars.yml

---
partitions:
  - number: 1
    start: 1MiB
    end: 1000GiB

#  - number: 2
#    start: 1000GiB
#    end: 2000GiB



volumegroups:
  - vg: vgdata
    pvs: /dev/sdb1
     
#  - vg: vgdata1
#    pvs: /dev/sdb2
#    pe: 4

    
logicalvolumes:
  - vg: vgdata
    lv: lv01
    size: 100%VG
    name: lv01
#  - name: lv02
#    vg: /dev/sdb2
#    lv: lv02
#    size: 100%VG
    
filesystem:
  - fstype: xfs
    dev: /dev/vgdata/lv01

#  - fstype: xfs
#    dev: /dev/vgdata/lv02

  
mountargs:
  - path: /data
    src: /dev/vgdata/lv01

#  - patg: /ww
#    src: /dev/vgdata/lv02

编写LVM剧本

[root@master01 lvm]# cat my_disk.yaml

      when: item.name not in ansible_lvm["lvs"]

    ##磁盘格式化（filesystem模块)
    - name: Create a xfs filesystem on lvm
      filesystem:
        fstype: "{{ item.fstype }}"

    ##挂载LV
