/dev/mapper/luks-ab8911f9-b3a4-4f33-8b10-7e52c7217ae9 is active.
That's the problem. First use df or mount to see if this device has a
mounted filesystem, and if so unmount it. Then you need to close it.
cryptsetup luksClose luks-ab8911f9-b3a4-4f33-8b10-7e52c7217ae9
Now you can wipefs the md127 device, then stop the array, then wipe
the members of the array.
