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:

# df -h

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?

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. :-)

Oliver
