# This playbook was made to automate Ceph servers maintenance
# Typical use case: hardware change
# By running this playbook you will set the 'noout' flag on your
# cluster, which means that OSD **can't** be marked as out
# of the CRUSH map, but they will be marked as down.
# Basically we tell the cluster to don't move any data since
# the operation won't last for too long.
- hosts: <your_host>
gather_facts: false
tasks:
- name: Set the noout flag
ansible.builtin.command: ceph osd set noout
delegate_to: <your_monitor>
- name: Turn off the server
ansible.builtin.command: poweroff
- name: Wait for the server to go down
syntax: change local_action syntax Use a nicer syntax for `local_action` tasks. We used to have oneliner like this: ``` local_action: wait_for port=22 host={{ hostvars[inventory_hostname]['ansible_default_ipv4']['address'] }} state=started delay=10 timeout=500 }} ``` The usual syntax: ``` local_action: module: wait_for port: 22 host: "{{ hostvars[inventory_hostname]['ansible_default_ipv4']['address'] }}" state: started delay: 10 timeout: 500 ``` is nicer and kind of way to keep consistency regarding the whole playbook. This also fix a potential issue about missing quotation : ``` Traceback (most recent call last): File "/tmp/ansible_wQtWsi/ansible_module_command.py", line 213, in <module> main() File "/tmp/ansible_wQtWsi/ansible_module_command.py", line 185, in main rc, out, err = module.run_command(args, executable=executable, use_unsafe_shell=shell, encoding=None, data=stdin) File "/tmp/ansible_wQtWsi/ansible_modlib.zip/ansible/module_utils/basic.py", line 2710, in run_command File "/usr/lib64/python2.7/shlex.py", line 279, in split return list(lex) File "/usr/lib64/python2.7/shlex.py", line 269, in next token = self.get_token() File "/usr/lib64/python2.7/shlex.py", line 96, in get_token raw = self.read_token() File "/usr/lib64/python2.7/shlex.py", line 172, in read_token raise ValueError, "No closing quotation" ValueError: No closing quotation ``` writing `local_action: shell echo {{ fsid }} | tee {{ fetch_directory }}/ceph_cluster_uuid.conf` can cause trouble because it's complaining with missing quotes, this fix solves this issue.
