I tried to delete the MDX, I removed the disks by failing them, then removing each array md0, md1 and md2.
I also did

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


Clearing the initial sectors doesn't do anything to clear the data in the partitions.  They don't become blank just because you remove them.

Partition your drives, and then use "wipefs -a /dev/sd{b,c}{1,2,3}"


I do NOT WANT this to happen, it creates the same "SHIT" (the incorrect array) over and over again (systemd frustration).


What makes you think this has *anything* to do with systemd? Bitching about systemd every time you hit a problem isn't helpful.  Don't.
