Red Hat Bugzilla – Bug 486661
Grub can't boot with GPT labelled disk
Last modified: 2014-03-31 19:44:51 EDT
This is a problem with disk setups >2TB, since that's the max size that MSDOS label can address.
I have 6 1TB drives in a DELL 2950 (with no more space for boot device), which forces me to create 2 RAIDs, instead of using 1 HW RAID5 over all 6 disks.
GPT support is in F12 as part of UEFI, and will be picked up for RHEL6. We're still validating >2TB disk support, but that is tracked in 203383 so I'm closing this as a duplicate.

BTW, if you are a hardware partner who would like us to test this with your card and UEFI firmware, please contact us!
