[Bug 1057444] Re: Unable to install GRUB on a hard disk for server installation with RAID

[Imran Chaudhry]

I was about to report a similar issue. My issue was with HDDs >2TB in
size with GPT partition table with Software RAID1.

I reported the issue along with a solution here:

This problem also exists in the CentOS 7 installer.
