Hi guys
Am I in trouble? Yes I am. :-o
Got a server that has been running for half a year .. and now .. it just will not boot. Grub complains with this error:
Error 18: Selected cylinder exceeds maximum supported by BIOS
I havn't changed anything with the hardware. The only thing that has changed is regular updating.
Could some Grub update be the problem here - and how do I revert if that is the case?
Regards Sticky

Can you choose a different kernel from the list in the grub menu and boot that instead? Check your BIOS hard drive mapping and make sure the geometry has not changed - maybe your CMOS battery has reset and lost a bunch of settings?
Re: Grub Error 18
Trying to boot the older kernel's produce the same error, while booting the win7 installation on the same disk (which actually is a raid1) works just fine.
Could some strange disk error produce this problem? - and is there a way to check the mirror for errors using rescue-mode with a installation media?

Re: Grub Error 18
I've seen this before on the forums and it has to do with the RAID 1. Can you post your /boot/grub/grub.conf here? Might have to boot from rescue disk to do so.
The problem is that grub asks the device for its geometry and the BIOS for the limits from which it can boot and the RAID 1 "disk" returns some bogus geometry with about a million cylinders and it looks to see where the kernel is on there and gives up.
