Re: Changing boot disk from secondary IDE to primary IDE and addinganother drive

[Mark Bruen]

Thanks for the input, it turns out that anaconda takes care of everything 
except the "swap" partition definition in /etc/fstab which I modified from 
hdc8 to hda8. My problem was that the disk I was adding had another install of 
redhat on it and the labels were the same as my original boot disk. After 
reading the boot messages carefully I noticed the "duplicate label" error 
message for the root (/) filesystem. I then booted from CD in rescue mode and 
removed all of the partitions on hdc (the new drive) and all worked fine. I 
then just created a new partition on hdc (hdc1), made a filesystem with mkfs 
and mounted it. I added it to /etc/fstab so it mounts at boot.
Thanks again.

On redhat 9 I'm currently booting from the secondary IDE first drive (hdc). I 
tried adding a drive to the primary IDE first drive (hda). The system booted 
but could not attach the swap partition on hdc. I'd like to put my current 
drive on the primary IDE first drive (hda) and the additional drive on the 
secondary IDE first drive (hdc). Do I need to change all config file 
references from hdc to hda prior to shutting down redhat? Are there any other 
config commands I need to run or grub commands at boot time?
Thanks.


i'm not going to guarantee that this will work, but if you're using
GRUB as a boot loader, there is a file /boot/grub/device.map that
you might be able to tweak to specify your boot disk.
on my system, the contents are:

  # this device map was generated by anaconda
  (fd0)     /dev/fd0
  (hd0)     /dev/hda
but i've never had any need to play with this, so i'm only 
throwing out a suggestion.

  anyone want to clarify this?
