I have checked the output of some older config files like
vg01.conf.[1-6].old and have found one without the additional hard disk.
Hence no data is stored on that disk yet, I wouldn't mind to overwrite
the configuration, but is it save doing it? I definitely worried about
data loss then.
Thanks,
Stephanus
