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.
Start with /r/LinuxQuestiond maybe? This here definitely is the wrong place.
Thanks, there is also /r/sysadmin and probably more where to ask, but i figured this place would also make sense. Its about where to get paid help for upgrades etc.
/r/sysadmin is also a terrible choice but go ahead, good luck.
at least thanks for the good luck wishes then! :)
You can also join the AlmaLinux chat and ask in the general channel, or in the migration channel.
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.
“Some” downtime. Probably multiple weeks 😅
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.
