If it is, when you type 'root > (hdX,0)' it should report that a file system was found. The 'setup > (hdX)' will tell grub to write the MBR to the specified disk. THANK YOU! I could have used that once or twice, and had no idea that grub could create a std. MBR.
When I set up a RAID 1, I do it like this:
device (hd0) /dev/sda root (hd0,0) setup (hd0) device (hd0) /dev/sdb root (hd0,0) setup (hd0) device (hd0) /dev/sdc root (hd0,0) setup (hd0)
This way, all the drives are set up as if they are hd0. This way, any of them will boot normally as a stand-alone drive.
Bowie, in terms of RAID 10, each drive technically cant be standalone right? The drives are striped and mirrored.
