I've been working on setting up a system with a bunch of hard disks. My latest attempt at an install is working but when I:
GRUB> root (hd0,0)
I get a no such partition error. Same thing if I use geometry to see what hd0 looks like to GRUB.
However, if I FDISK -l all the partitions get listed and everything looks normal.
For the record, I'm trying to RAID1 hd0 and hd1 following an online how-to.
Here's the history of what I've done so far:
Six IDE hard drives. One on each MOBO controller. Two IDE PCI expansion cards w/ one hd on each controller on each card.
Original install had a problem with the menu.lst and device.map files not agreeing. I edited them and the system would then boot normally.
An FDISK -l looked good but, there was no "boot asterisk" by sda1. I figured out how to mark it as a boot in FDISK and did that and now it shows the asterisk by sda1.
BTW, MOBO drives show up as sd not hd, that is where the original booting problems started. (Yes, they are on IDE controllers not SCSI.)
So, the question is.... where does GRUB get its partition information? And why can't it see the partitions that FDISK can? And how do I fix it?
Thanks,
John
