You may need more than one node to reproduce the problem. I had a 3 node system.
I ran do-release-upgrade on node 1. The OSDs on node 1 connected to the monitor quorum, which had un- upgraded monitors on hosts 2 & 3. The upgraded OSDs on node 1 immediately died and could not be revived. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1874939 Title: ceph-osd can't connect after upgrade to focal To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ceph/+bug/1874939/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
