[Linux-cluster] Clearing Dead Volumes

[isplist at logicore.net]

A while back, my storage was changed without the nodes getting a chance to be 
disconnected from the storage. 

At this point, firing up the nodes has all of them seeing a lot of garbage 
data in place of what used to be their storage volumes. What is the best way 
of clearing this old data so that I can re-create the proper storage devices?
