Description of problem:
See FC bug: https://bugzilla.redhat.com/show_bug.cgi?id=623597
Grub will not load on a disk larger than 1 TB.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Create a single Raid 5 partition larger than 3 TB & run the default RHEL Install.
After reboot it will stop at the "grub>" prompt. When you manually enter grub commands you will get the error:
Error 18: Selected cylinder exceeds maximum supported by BIOS
Grub menu / system login
Which is it? 1TB or 3TB?
Please read the referenced FC bug report. I don't know exactly where the limit lies and it may be (somewhat) dependent on the architecture of the (virtual) drive. The initial reporter stated that he had problems with 1.5TB drive. My original configuration was with a 3+TB. My guess is that it is slightly over 1 TB.
I've successfully used 2TB drives to boot from, so this appears to be a problem with >2TB boot volumes. This is unsupported on BIOS machines.
