Greetings:
I'm upgrading a fileserver running 3.4 (upgrade to a larger disk). I backed up the data from the "old" disk and slapped in a newer, larger disk and installed Centos-3.4. No problems.
Now, there are some files on the "old" disk that I forgot to move to the back-up disk, so I'd like to mount the "old" disk as /dev/hdd and reboot the system and transfer the files [hdd (old disk) --> hda (new disk)].
However, the old disk still has Grub on the MBR and when I boot, the system tries to mount the "/boot" and "/" partitions from BOTH disks! I get errors about duplicate partitions and that those dups won't get mounted.The fileserver does boot but with a configuration combination of both systems.
Question: Grub is correctly installed and configured on hda. How do I get the boot process to ignore the old disk (and MBR) on hdd???
I tried google but I can't seem to find this fix.
Is it possible that the old disk and the new one have the same label name?
That is the only reason I could think of why it would try to mount or confuse the disks.
If that is the problem, you can boot via CD-1 and use "linux rescue" then relabel the hdd disk to something else using the command:
e2label /dev/hdd# e2label /dev/hda#
If they are the same ... relabel hdd with the command:
e2label /dev/hdd# new_name
(the # is the specific partition number)
