cephadm: error: unrecognized arguments: --zap-osds

[sebastian-philipp]

Turns out, cephadm-ansible is a bit ahead of Ceph here. If you see this error

    usage: cephadm [-h] [--image IMAGE] [--docker] [--data-dir DATA_DIR]
                   [--log-dir LOG_DIR] [--logrotate-dir LOGROTATE_DIR]

    cephadm: error: unrecognized arguments: --zap-osds

Simply remove this argument from the playbook, till 16.2.5 is released.

given only rhcs or dev deployments will have the '--zap-osds' parameter, one option would be to do something like following as a workaround until 16.2.5 is out:

    - name: purge ceph cluster
      command: "cephadm rm-cluster --force {{ '' if ceph_origin == 'community' else '--zap-osds' }} --fsid {{ fsid }}"
      when: group_names != ['clients']
