Description of problem: Recently I worked on the RHCS upgrade (4.x to 5.x) scenario with a host OS upgrade. The procedure involves backing up ceph files (/etc/ceph/, /var/lib/ceph, ceph-ansible config files incase of ansible node), once os upgrade is done user will have to restore the files, change ownership of restored files and might involve starting up the services. Found it tedious to do these on a test cluster with 4-5 nodes, which makes me think that it would be more nice if we can provide some usability enhancement to users to handle their clusters in these scenarios. How about ceph-ansible 6.x (RHCS 5.x) to have a playbook which assists user with these manual tasks ? Something like - User to install ceph-ansible 6.x on a rhel-8 node - runs playbook for each node on rhel 7 - ceph-ansible to take backup of required files and save it in the new node - User upgrades his node to rhel-8 one by one - user runs restore playbook each time a node gets upgraded to rhel-8 - which should restore all files on that particular node and assists users in starting all services on that node which were running before if required Version-Release number of selected component (if applicable): Latest 5.x Steps to Reproduce: 1. Configure 4.x cluster on rhel-7 2. Try to upgrade cluster to 5.x following docs (involving host OS upgrade from rhel-7 to rhel-8) Actual results: User has to follow many mnual steps Expected results: ceph-ansible helping users in reducing backing up and restoring process Additional info:
