Installing Grub2 on /dev/sdc giving warning and an error.

[Aero Maxx]

Hi Everyone,

I've just installed Fedora 17 as a fresh install and setup Raid 10, its 
all working, and does boot ok.

However when installing grub on each of the 4 drives one of them doesn't 
like it, or something isn't right and I am not sure what the issue is as 
the 3 drives don't complain.

I have a 500mb raid partition on each of the 4 drives, and then have 
created a raid 1 device that is mapped to /boot mount point.

the rest of the space is also assigned a fixed size and mapped to a raid 
partition, I have then created a raid device which is mapped to a LVM, 
and then created the usually group, and the lv_root, lv_swap, lv_home 
groups within it.

I have then done grub2-install /dev/sda, this returned "Installation 
finished. No error reported" as did /dev/sdb and /dev/sdd.

When I did grub2-install /dev/sdc this came back with a warning and a 
error of the following, then quits back to the prompt, it boots ok is 
this anything for me to worry about ?.

/usr/sbin/grub2-bios-setup: warning: this GPT partition label contains 
no BIOS Boot Partition; embedding won't be possible.
/usr/sbin/grub2-bios-setup: error: embedding is not possible, but this 
is required for RAID and LVM install.

Thanks
Daniel.
