Chris,

I just created a lv for testing purposes without defining the stripe size.
Wanted to know how to undo/delete it.  Ed's response regarding lvremove led
me to the verious lv* and vg* commands needed to clean it up nicely.

That's a good point.  This is getting a little off thread, but what is the
speed and/or other differences between setting up a software RAID0 across
two devices and doing the pv,vg,lv dance between two devices?  Well, I guess
resizing would be nicer under LVM, or would it?

Thanks,

Monty
