Ansible: create Volume Groups & filesystems on AIX

Today we are going to create a Volume Group and a list of JFS2 filesystems programmatically using Ansible on an AIX 7.x system. Let’s not make you languish any further, here we go:

- name: Create stuffvg and its filesystems
  hosts: target
  remote_user: root
  collections:
    - ibm.power_aix
  var:
    prefix: "stuff"

  tasks:
  - name: Be sure the wanted disks are usable with a cfgmgr
    ansible.builtin.shell: cfgmgr

  - name: Create "{{ prefix }}vg"
    ibm.power_aix.lvg:
      state: present
      vg_name: "{{ prefix }}vg"
      pvs: hdisk1
      vg_type: scalable

At this stage we already have a scalable Volume Group named stuffvg. Now, let’s add some filesystems in it but first thing first, we then need to create the jfs2log LV:

  - name: Create the jfs2Log lv
    aix_lvol:
      vg: "{{ prefix }}vg" 
      lv: stuffj2log
      lv_type: jfs2log
      size: 128M

  - name: Logform the jfs2log
    ansible.builtin.shell: yes | /usr/sbin/logform -V jfs2 /dev/stuffj2log

Now we are ready to create our Logical Volumes:

  - name: Create LVs
    aix_lvol:
      vg: "{{ prefix }}vg"
      lv: 	"{{ item.name }}"
      lv_type: 	"{{ item.type }}"
      size: 	"{{ item.size }}"
    loop:
      - { name: 'stuff_users',	type: 'jfs2', 	size: '20G' }
      - { name: 'stuffora19c',	type: 'jfs2', 	size: '2G' }
      - { name: 'stuff_ora', 	type: 'jfs2', 	size: '3G' }

Now it’s time to create JFS2 filesystems on our freshly made LV, and to mount them:

 - name: Creation of JFS2 filesystems
    ibm.power_aix.filesystem:
      state:		present
      device: 	  	"{{ item.device }}"
      filesystem: 	"{{ item.mountpoint }}"
      fs_type:		jfs2
      auto_mount:	true
    loop:
      - { device: 'stuffora',	        mountpoint: '/home/oracle' }
      - { device: 'stuff_users',	mountpoint: '/home/users' }
      - { device: 'stuffora19c',	mountpoint: '/home/oracle/product/v19c' }

  - name: Mount FS
    ansible.builtin.shell: mount "{{ item }}"
    with_items:
      - "/home/oracle"
      - "/home/users"
      - "/home/oracle/product/v19c"

Last but not least, some exotic stuff to finish, as I know you are kind of that:

  - name: chlv -x 3000 hd1
    ibm.power_aix.lvol:
      vg: rootvg
      lv: hd1
      extra_opts: "-x 3000"

  - name: Increase size of a filesystem
    ibm.power_aix.filesystem:
      filesystem: /home
      state: present
      attributes: size=25G

And here we are. No more excuse to create twice the same FS. I’ll see you next time.
