Hi Johnny,
thank you very much for clarification.
You said that in the centos infrastructure only one server got the
problem.
What are the conditions that permit the breakage? There is a particular
configuration (hw/sw) case that match always the problem or it is
random?
Thank you
I have two servers running Centos 7 on apple hardware (one mac-mini
and one mac server). They both failed to reboot a few days ago. So
perhaps whatever anti-boot bug hit Centos 8, also hit Centos 7. I
can't tell what version got updated since the system simply fails to
boot. I don't even get a grub screen. I'll have to rebuild the
systems from scratch.
You should be able to boot off of installation media into rescue mode,
and downgrade the grub2* and/or shim* RPMs.
