# NOTE (leseb):
|
||
|
# The playbook aims to takeover a cluster that was not configured with
|
||
|
|
# ceph-ansible.
|
||
|
|
#
|
||
|
|
# The procedure is as follows:
|
||
|
|
#
|
||
|
|
# 1. Install Ansible and add your monitors and osds hosts in it. For more detailed information you can read the [Ceph Ansible Wiki](https://github.com/ceph/ceph-ansible/wiki)
|
||
|
|
# 2. Set `generate_fsid: false` in `group_vars`
|
||
|
# 3. Get your current cluster fsid with `ceph fsid` and set `fsid` accordingly in `group_vars`
|
||
|
|
# 4. Run the playbook called: `take-over-existing-cluster.yml` like this `ansible-playbook take-over-existing-cluster.yml`.
|
||
|
|
# 5. Eventually run Ceph Ansible to validate everything by doing: `ansible-playbook site.yml`.
