Cleaning sticky DMraid metadata

You may have run into sticky dmraid metadata that doesn’t want to be removed no matter what you do.

Run the following comment on your drive

dd if=/dev/zero of=/DEV/ bs=512 seek=$(( $(blockdev --getsz /DEV/) - 1024 )) count=1024

Replace /DEV to the drive that contain the metadata. Perform a reboot once the command has been run.

Voila!
