I have a Dell R710 that has 6x1TB in a RAID-5 configuration. When installing CentOS 7 using the full disk capacity and booting in UEFI mode the machine dumps me into a GRUB rescue mode prompt.
error: disk `,gpt2′ not found
Entering rescue mode…
If I use the PERC RAID controller to make the disk smaller ROOTDISK volume of 100GB in size and then a DATA volume of the rest of the disk the system boots just fine so this seems like a GRUB2 issue. Any thoughts?
