Facing various issues in getting it done, please note as below and suggest: issue 1: when updating the all.yml file with ceph release number to 16 and and ceph release as Pacific: *TASK [ceph-validate : validate ceph_repository_community] ************************************************************************** *task path: /home/ansible/ceph-ansible/roles/ceph-validate/tasks/main.yml:20Tuesday 23 March 2021 10:00:09 +0530 (0:00:00.141) 0:01:06.028 *********fatal: [cephnode1]: FAILED! => changed=false msg: ceph_stable_release must be either 'nautilus' or 'octopus'fatal: [cephnode2]: FAILED! => changed=false msg: ceph_stable_release must be either 'nautilus' or 'octopus'fatal: [cephnode3]: FAILED! => changed=false msg: ceph_stable_release must be either 'nautilus' or 'octopus'* *Issue 2: by keeping the ceph_stable_release to octopus and changing the ceph release number to 16 it gives error as :* *fatal: [cephnode1 -> cephnode1]: FAILED! => changed=true cmd: - ceph - --cluster - ceph - osd - require-osd-release - pacific delta: '0:00:00.478257' end: '2021-03-22 19:54:22.892994' invocation: module_args: _raw_params: ceph --cluster ceph osd require-osd-release pacific _uses_shell: false argv: null chdir: null creates: null executable: null removes: null stdin: null stdin_add_newline: true strip_empty_ends: true warn: true msg: non-zero return code rc: 22 start: '2021-03-22 19:54:22.414737' stderr: |- Invalid command: pacific not in luminous|mimic|nautilus|octopus osd require-osd-release luminous|mimic|nautilus|octopus [--yes-i-really-mean-it] : set the minimum allowed OSD release to participate in the cluster Error EINVAL: invalid command stderr_lines: <omitted> stdout: '' stdout_lines: <omitted>* Problem Statement : Not able to upgrade to the upper version of Ceph-ansible from octopus to Pacific.
