Problem with GPT and a 12TB RAID-5 partition

[Stephan Hermann]

Moins,

I wonder if grub / grub_pc is able to boot from gpt partitions.

and the partition "gpt-bios" is not know, you should declare it as
"gpt" in setup-storage disk config, e.g.


 
disk_config disk1 disklabel:gpt fstabkey:uuid
primary -              0-       -       -



(this definition is for a drbd device, so you need to configure your fs
etc.)

 Regards,

\sh
