The idea is to boot a disk in an mbr fashion while using the GPT (not filesystem) label to detect the disk. That is useful when you use grub2 & gpt. I was in case where my nodes (100s) have 8 disks each and no guarantee of which disk is "bootable" in the disk. This way I can tell "please boot the disk that have one partition labelled "xyz"". So nothing related

Hello Everyone, I am a newbie. When I try to install GRUB2 on centos 5.2 system, I get following error. centos5: grub-install /dev/sda //sbin/grub-setup: warn: This GPT partition label has no BIOS Boot Partition; embedding won't be possible!. //sbin/grub-setup: warn: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE

I''m currently researching an upgrade to (raid1-ed) btrfs from mostly reiserfs (which I''ve found quite reliable (even thru a period of bad ram and resulting system crashes) since data=ordered went in with 2.6.16 or whatever it was. (Thanks, Chris! =:^)) on multiple md/raid-1s. I have some questions that don''t appear to be addressed well on the wiki, yet, or where
