Description Coady LaCroix 2018-09-24 22:20:52 UTC
Description of problem:
No documentation around the process to convert a non-containerized ceph cluster to a containerized one currently exists. The Ceph QE team has a high priority item to automate this use case. The ceph-ansible playbook exists for this procedure (switch-from-non-containerized-to-containerized-ceph-daemons.yml) but there is no documentation describing necessary configuration, process, usage, etc.

Version-Release number of selected component (if applicable):


How reproducible:
100% - no doc exists

Steps to Reproduce:
N/A

Actual results:
  The playbook for this procedure has not been verified and documentation does not exist

Expected results:
  Ceph documentation to provide supported usage of this playbook.

Thanks Noah! Coady, you can use Noah's doc for testing while the docs team translates this to the CMS.

I've attempted to execute this according to the docs and have hit an issue. I filed another bz and updated the depends_on field here.

Updating the QA Contact to a Hemant. Hemant will be rerouting them to the appropriate QE Associate.

Comment 22 Vasishta 2021-06-11 07:43:53 UTC
We are providing container details of RHCS 4.x here
Migration should happen from 3.x baremetal to 3.x containerized

Also, I'm confused on relevance of this procedure in RHCS 3.x
(I think there were some open issues with this migration in 3.x and this procedure might not be supported)

Comment 23 Vasishta 2021-06-11 14:44:51 UTC
Hi Ranjini,

Since this is RHCS 3.x, we need to ask users to copy playbook to /usr/share/ceph-ansible and initiate playbook
Please refer installation guide. (Section 4.1 - step 12 and 14

Comment 25 Vasishta 2021-06-14 14:25:01 UTC
Hi Ranjini,

In Both syntax and example of step 3 
>> ./infrastructure-playbooks/switch-from-non-containerized-to-containerized-ceph-daemons.yml
 needs to be changed as
>> switch-from-non-containerized-to-containerized-ceph-daemons.yml

(We have already asked users to copy it from infrastructure-playbooks directory.

Vasishta Shastry
