3 node compact clusters seem to struggle with upgrades, the cordoning prevents necessary pods from coming online and often do not uncordon. SNO clusters almost always need hand holding.

When the node drain gets stuck I have to manually force a drain. I drain one node at a time, not really a good idea to brute force across all hosts at once. Take the time to handle each node one at a time. oc adm drain master1 --ignore-daemonsets --delete-emptydir-data

Sometimes I'll see the MCP still hung on that node/master, at which point I'll give it a kick with touch /host/run/machine-config-daemon-force

If the mcp and/or machine-config operator continue to fail for the node I'll go kick it harder with
