Elevate to Alma Linux 8 goes to Grub Rescue
I'm trying to upgrade CentOS 7 to AlmaLinux 8
I've used Elevate script and everything seems to be working properly until my server won't boot.
I enabled KVM and shows GRUB Rescue.
I can't find any errors.

I can't understand what's wrong with Grub.
At first I taught it was lack os space, but al the kernel files seems to be generated correctly.
Then something with BLS, but was not the case either. (https://www.linode.com/community/questions/23142/almalinux-86-grub-2-boot-failures-and-resolution)

Have you forcefully rebooted the server after it didn't come back online? Stage 4 could take up to 20-30 minutes and if the server was rebooted during the process it could result in a corrupt system.
How did you elevate the server exactly? What command(s) did you use?

I did reboot the system, only 3 hours after
I follow this guide: https://cpanel.github.io/elevate/
wget -O /scripts/elevate-cpanel \ https://raw.githubusercontent.com/cpanel/elevate/release/elevate-cpanel ; chmod 700 /scripts/elevate-cpanel/scripts/elevate-cpanel --check --upgrade-to=almalinux/scripts/elevate-cpanel --start --upgrade-to=almalinux0 -
It is hard to say without having a look at the system. Reinstalling grub might do the trick on the drives. It could also be a bug as per:

I had the same issue - ARG! System won't boot while upgrading to Rocky 8 – cPanel - I got no support from hetzner at all, my first point of call now is to cancel cpanel through them and go direct.
I also got into rescue and tried a bunch of things, couldn't find any solution, so gave up and re-installed whm from scratch and restored all my accounts (After wasting 24hours of no support or getting anywhere) - I hope you do find a solution!
to get into the os - you will need to know which drive is which, your setup is different to mine, but mine was:
mount /dev/md2 /mnt
mount --bind /dev /mnt/dev
mount --bind /proc /mnt/proc
mount --bind /sys /mnt/sys
mount /dev/md1 /mnt/boot (I think boot)
chroot /mnt0 -
I cant mount boot directly from /mnt
I did
root@rescue ~ # mount /dev/md1 /mnt/boot
root@rescue ~ # mount -o bind /mnt/boot/ /mnt/md2/bootNow I tryed to change GRUB_ENABLE_BLSCFG to false in /etc/default/grub
Still no luck

Do you have a storage box on hetzner? I already had a backup, but before I wiped I zipped up the whole home folder and scp'd it to the storage box

My last backup was made 31/12 :(
1 Backup for week, I thought it was a secure upgrade, I was wrong.
They should warn all users that is not safe. Better to start fresh and migrate accounts.

Pires,
It is marked as experimental. It is shown on the github page you pulled the script from. After you chroot into your system fro rescue you should be able to reinstall grub with "grub2-install /dev/X" replace X with your drive name i.e sda,sdb,nvme etc... thereafter you can run grub2-mkconfig to re-generate the config files.
otherwise restoring everything from backups would be the best alternative.

If you have a storage box - gzip and upload, then restore from your backup, and then unzip over the top... I agree, my impression was 30mins job done. 3 days later I'm still sorting the aftermath, wish I hadn't done it now.

I don't usually do this kind of thing, but the occasion is worth it. Today this crack AndrewN solved a problem for me that may be simple for many but for us it was a big headache. He really is an excellent professional and if you really need serious, fast and honest support... you should contact him.
