Hey all,

Doing some testing and would like to ask for some pointers to further my tests. I've successfully set up a cluster using kolla-ansible with Ceph and numerous other services. My tests have gone well (barring a few initial issues) and migration from oVirt also tested well. I'm finally at the point where I'm testing and looking into DR and Backups. I've read the documentation pertaining to MySQL backup and restore, that is clear enough. I've also checked out backing up and restoring Ceph in case of major outage, what I can't quite figure out is the following scenario:

For some reason, I need to re-deploy my cluster, however ceph nodes are still fine and didn't loose data. I'm sure that the restore will point everything to the right place and I'll be able to pick up where I left off. What I need help figuring out so far is how I connect my previous ceph nodes to the new deploy.

I've done a redeploy and everything seems fine, however none of my OSDs show up. I need to bootstrap my ceph nodes again for kolla-ansible to configure things properly. I have zero doubt it's a stupid issue on my end and something I'm missing for sure, so would appreciate a pointer in the right direction.

TIA, P.
