Hi Paul,

Can you try: # vgreduce -v VolGroup00 /dev/hdb1
That did the trick. This is the first time I'm working with LVM, but meanwhile I love it. I moved everything and finally have the following configuration:

The last thing before I can boot from my drive is to copy the MBR.
# grub-install /dev/hdb /dev/hdb does not have any corresponding BIOS drive.
What does that mean?
What's in your /boot/grub/device.map ?
Perhaps you could try "grub-install --recheck"?
The other thing you need to bear in mind is that although you are installing grub on hdb, when that version of grub is loaded it will be on "hda". So a bit of trickery is needed. This is not something I've done before, but I think it goes like this:
# grub grub> device (hd0) /dev/hdb grub> root (hd0,0) grub> setup (hd0) grub> quit
Perhaps a grub expert could confirm that?
Finally one last question: do you think it's a good idea to use this "old" disk within a RAID 1? It would be a nice exercise for me anyway. :-)
Yes, you could do that. It would be another "tricky" operation though, since neither of your current drives are part of a raid device. Best leave that for another thread I think.
Paul.
