Hi, I have come across this issue on one of ceph cluster storage nodes. (in the production OpenStack). Now, I would like to redploy the CEPH and start OSD on this node again with the same version. I will try to upgrade to a newer version, after increasing the capacity of cluster storage and bring the ceph health status to "OK" status. Has any one used, kolla ansible to deploy or add new node the existing ceph cluster storage. let me know the steps. What I have tried: 1. Ran "ceph playbook from kolla-ansible $ kolla-ansible bootstrap-servers -i <path/multinode> --limit nodeXX.maas Output: success 2. Unable to go through the "prechecks" as docker deamon is not running. 3. Could not start the docker, Uninstalled docker and during installation of docker using the docker-install/site.yml the docker could not start docker neither install nor start the docker because it is looking for dependencies of OSD device (disk) 4. Trying to uninstall the docker completely from physical node and insgtall docker from scratch and reset up the CEPH on this node? Has anyone tried resetup CEPH OSD on the existing ceph cluster storge.
