Hey folks. I keep putting it off, but I need to move it forward, so I am proposing to move batcave01 to rhel9 tomorrow, starting at 21UTC.
My plan is roughly:
- sync data from batcave01 to batcave02 - at 21UTC take down services on batcave01 - sync data again - take batcave01 down. - rename batcave02 to batcave01 and re-ip it to the right IP - reboot it back up as batcave01 - Fix any issues that come up.
This means that the ssh host key for batcave01 WILL CHANGE! If you are using https://admin.fedoraproject.org/ssh_known_hosts in your ~/.ssh/known_hosts it shouldn't matter. If you aren't you may have to accept the new changed host key.
For the time when I am switching things, EPEL builds may fail. This is because koji pulls RHEL packages from batcave01. I would expect this to be a very short window.
The playbook completes fine on batcave02 and as far as I can see things should work fine there, but there may be some broken items. Please file tickets/let me know if you find anything like that.
In the event that things go very poorly for some reason, I can always bring the old vm back up and we can revert to it.
Thanks,
kevin
