I've searched through the forums and I get pieces of what I might need to do, but I can't find anything specific to what I want to do.
I just got two Samsung 2 TB hard drives that I want to boot into a mirrored RAID 1. Unfortunately, I can't set any partition to be bootable. If I let the install continue, when it gets to the point of installing GRUB it bombs out that it can't install GRUB on sda.
Apparently, the issue is with having >=2TB drives. I did some searching and found tips about getting GRUB installed manually, but all of the topics seem to refer to a single disk. But when it comes to a bootable mirror, the vast majority of what I'm finding says to use the alternate CD and create the mirror from the start of the build. Well, that's what I'm trying to do but I'm getting slammed by this 2TB issue!
I'm halfway tempted to install Solaris x86 and mirror the disks with DiskSuite (SVM) if they accept the 2TB disks, but I'd like to stay with Ubuntu.
Would I be better off booting of disks that are less than 2 TB? I planned on adding my existing 1.5 TB disks later to make a 3.5 TB mirror; but if it's easier to boot from 1.5 TB disks and add the 2 TB as extra storage, so be it. (I can't add the 2TB disks to my existing server because there aren't enough SATA ports and I don't want an expansion card as another point failure.)
Has anyone successfully been able to mirror 2TB disks together without having to do a ton of steps?
