Why does ansible gluster_volume module run a remove-brick operation while modifying volume options?

Issue

• Modifying the options of an existing Gluster volume using ansible playbook leads to remove-brick command.

tasks:
  - name: "Set the retention-period to 120s"
    gluster_volume:
      state: present
      name: "volume1"
      options:
        { features.default-retention-period: "120" }


# ansible-playbook gluster_vol.yaml
