I will try this, however, these errors occur prior to the filesystems
being initialized. Also, I decided to try to delete the PV. I deleted
the LV, but every time I tried to delete the VG, I get

[defiant /home/storm]# vgchange -a n vg01
vgchange -- volume group "vg01" successfully deactivated

[defiant /home/storm]# vgremove vg01
Segmentation fault

The logs show the following:

Originally, I had the drives on one IDE channel (hda and hdb) and the
DVD and CDRW on another (hdc and hdd). I now have drive 1 on hda, dvd on
hdb, drive 2 on hdc and cdrw on hdd. Same indications.

How should I know if it works?  That's what beta testers are for.  I
only coded it.
