(this is from my desktop, but the same updates hit the server).

Our server cannot start, I can only get to a rescue prompt with disks mounted as read only. I can see a short message about a efisk error imediately before grup is loaded:
error: efidisk read error.
I think this means a reinstall which is pretty crazy on a production server.

NB: I had to choose UEFI boot to have support for a 5,2 TB disk.
