Harry - Thanks for your response. I tried this and got a new message on boot: mount: label=/root duplicate - not mounted I guess this means I will have to relabel all six of the partitions on my second drive? Sounds like time for a rant (at Red Hat, Harry, not at you): Why can't RH9 understand the difference between "hda /label" and "hdb /label"? Especially considering that RH7.3 apparently has no problem with this. Even Windows can do this. Relabeling hdb partitions will not work in my application, which is using the second drive as a backup. Ideally, I would use dd to copy all the partitions from hda to hdb every night. If hda crashes, all I have to do is change the jumpers for master and slave, and I'm up and running on hdb. Been doing this for years with RH7.3. Now I'm back to square one. Is there any way to make a backup this accessible without adding hardware? -Glenn. Harry sez: "The problem is that on each disk you have a partition labeled as "/". The program e2label uses partition lables so that even if the device number changes mount is still able to figure out which partition is supposed to be "/". "The easiest way to do this is to boot the system with the install CD choosing "linux rescue" as the boot option. Ensure that the rescue program doesn't try to mount your disks. "Then run: e2label /dev/hdb1 /YOURNAME HERE (or whatever the other drive is) "Then boot your system normally, edit /etc/fstab and add and entry for the new filesystem. "That should be all :-) "HTH, Harry" Quoting glenn <glenn@xxxxxxxxxxxxxx>: *> Here's the deal. I'm trying to add a fully-loaded RH9 IDE hard *> drive to a computer that already has one.
