spdk_bs_destroy is the programmatic way to do it.  Brute force looks something like this:

scripts/setup.sh reset
dd if=/dev/zero of=/dev/nvmeXnY bs=4096 count=1

You basically need to wipe the superblock from LBA 0.

    I need to destroy blobstore on a device if it exists, controller reset doesn't seem to do this so is the best way spdk_bs_destroy() or is there another way to reliably wipe a device?
