Hey Jeremi,
I'm not sure how ceph-ansible will handle a hybrid system. You'll need to make sure that you have the same info in the ceph-ansible "fetch" directory or it will create a separate cluster.
I'm not sure if you can somehow force this without causing some issues. I'm also not sure what other issues might arise.
Perhaps a way forward would be to start the osds by hand?
Something like:
sudo apt update
sudo apt install ceph
Get a copy of the /etc/ceph/ceph.conf and /var/lib/ceph/bootstrap-osd/ceph.keyring from another node.
sudo ceph-volume lvm zap /dev/sd?
sudo ceph-volume lvm create --data /dev/sd?
sudo apt install ceph
Get a copy of the /etc/ceph/ceph.conf and /var/lib/ceph/bootstrap-osd/ceph.keyring from another node.
sudo ceph-volume lvm zap /dev/sd?
sudo ceph-volume lvm create --data /dev/sd?

_______________________________________________Good dayWe currently have 12 nodes in 4 Racks (3x4) and getting another 3 nodes to complete the 5th rack on Version 12.2.12, using ceph-ansible & docker containers.With the 3 new nodes (1 rack bucket) we would like to make use of a non-containerised setup since our long term plan is to completely move away from OSD containers.How would one go forward running a hybrid environment in the interim until we've rebuilt all our existing osd nodes?I can assume that i would require a separate /ceph-ansible directory with site.yml to my existing site-docker.ymlWould I require separate inventory files, one for the existing 12 nodes & one for the 3 new nodes? How would I connect the new nodes to the current controller (mds,mgr, mon) container nodes?Regards
