Delete DMRAID Metadata Off A Harddrive

First step is to list all the DMRAID nodes

dmsetup ls

Which would spit something like this out:

ddf1_44656c6c202020201000006010281f0b3ad6cf283f12f2d4   (253, 0)

To delete that, you'd do the following:

dmsetup remove ddf1_44656c6c202020201000006010281f0b3ad6cf283f12f2d4

And that will free your drive of any existing or orphaned DMRAID metadata
