Enabling `microk8s_enable_HA: true` dosn't add nodes to master

[mosgjig]

Attempting to create a cluster with 3 raspberry Pi's.

The playbook to run the role:

---
- hosts: cluster
  gather_subset:
    - all_ipv4_addresses

- hosts: cluster
  # serial: 1
  gather_facts: yes
  roles:
    - role: istvano.microk8s
      become: true
      vars:
        users:
          - ubuntu
        microk8s_version: stable
        microk8s_enable_HA: true
        microk8s_group_HA: cluster

Logs don't indicate any issues when adding nodes to master. Performing a check on master doesn't show HA:

$ ansible cluster -i inventories/microk8s/hosts -m shell -a "microk8s status" --limit pimaster

Anything missing?

Closing issue... went in and purged microk8s from each server and re-ran the role with result:

ansible cluster -i inventories/microk8s/hosts -m shell -a "microk8s status" --limit pimaster
