I tried to use the elevation upgrade script from almalinux, however it fails. it ends with the screenshot i attached, emergency mode. and I was then required to roll back a snapshot. My current host was so kind to take a look as well, also try to upgrade it themselfs, but they couldn’t achieve it either on a quick try (i saw them through vnc also doing a drive repair)
I want to upgrade to almalinux 9 (through 8 then as required), so where does one get affordable and truthworthy help for these things, for the not-so-techy people like myself?
You should the share the contents of error file with whoever you’re asking help from.
Where does one get help? IT consultants. Where does one get affordable help? Dunno, I don’t use IT consultants.
Is there a particular reason you need to upgrade rather than back up your files, do a clean install of Alma, and then rsync your files back to the new host?
That’s what I’d do. I also run a lot of docker containers, so I am not worried about nuking a system — I can rebuild in minutes on a new VM.
Are the mods even active anymore? So many non-self hosting related questions…
I know this is probably not the answer you’re looking for, but at my work we never even do in-place upgrades from one version of rhel to the next. Always a fresh install on a new server, then migration of each service.
If that sounds painful, it could be a good opportunity to dabble in some configuration management (like Ansible) or at least thorough build docs of how to get a bare server into the state you want.
The steps would basically be:
- Fresh OS install on new server
- Install each application and get it running.
- One by one, stop the application, copy data (files and/or databases) from old server, start application, troubleshoot until it’s happy
- Switch DNS to new server
- Decommission old server
It’s a bit harder if it’s a physical machine and you can’t spin up a new one simultaneously. With that, you just have to make a backup to an external drive and schedule some downtime.
