Okay, now I know why I reported designate 

I was iterating through the systemd services and called stop against them..
For specific reason I have on controller0 set connection to DB to controller0 for designate

BUT as I stopped mariadb before designate .. designate didn't have mariadb available ..so it failed ..on controller1 should be OK in my env
