Yes, trailing / doesn't matter in the rm args :)

Good.

See below.

You still seem to have wrong /dev/ entries :-(
Maybe because of earlier problems, 2 VGs (volDisk and volDisk2) now
have the same internal number?
Please send the output of
"pvdata -a /dev/hd[cd]9 /dev/hda15 /dev/hd[cd]10 /dev/hda16 ; ls -lR /dev"
directly to me (mge sistina com).

If volDisk and VolDisk2 have the same internal numbers, we can try "vgscan -f"
which comes with LVM >= 1.0.3.
