In the process of upgrading from 7 to 8 something went wrong. At the moment my system boots only in recovery mode, because it cannot mount `/boot/efi`. Other people has discussed issues on boot/efi and were related to missing module for vfat. I think this is also part of my problem, as I do not have a vfat.ko anywhere in my filesystem. (I did `find / -iname vfat.*` and variants and no results to any search)
Also `modprobe vfat` says the module is not found, so I really think I have to install it! My problem is that I do not find what relevant package I should install via dnf.
For the record `uname -a` gives 3.10.0-957.el7.x86_64 #1 SMP date of 2018
How to install vfat module using dnf? or other installation methd?
Re: How to install vfat module using dnf? or other installation methd?
There is no supported upgrade from one major version to another. It's a backup/reinstall/restore/reconfigure scenario instead.
Your botched upgraded system has the wrong kernel. That is still a CentOS 7 (and very old at that) kernel. An el8 kernel would be 4.18.0-something.

CentOS 8 died a premature death at the end of 2021 - migrate to Rocky/Alma/OEL/Springdale ASAP.

Proceeding to upgrade to Alma 9 ... indeed.

If I may, in what sense an OS is "enterprise" if does not offer upgrades from one major to the next major release? How is one supposed to keep the system up to date? Reinstalling from scratch seems a thing of MS Windows (Win 9x maybe).

In enterprises hardware usually has a 3-5 year lifetime, and
RHEL+clones has ~10 years. So generally, the hardware is
obsolete before the OS runs out of updates.

Indeed.
There will be security and bug fixes all the way.
A different major version is a different set of features. If you have a server with your software stack and you change features of the platform that the stack depends on, then the stack, the server breaks.
It is not "from scratch". It is "clean install" + "deploy config" + make user data available.
The config is different for each major version, but not very difficult to adjust.
When you know the config for Alma 9, it is easy to deploy that to thousand systems.
If your user data is lost with system, then you did not have backup solution.
Enterprises do have proper backup.
A major version of RHEL has lifetime of a decade. The idea of "enterprise" is that you set it up and it runs the lifetime of the hardware.
