The next approach may be to just try to stop udev while ceph-volume
lvm zap is running.


I seem to recall some ticket where zap would "only" clear 100M of the drive, but lvm and all partition info needed more to be cleared, so using dd .... bs=1M count=1024 (or more!) would be needed to make sure no part of the OS picks up anything from the previous contents.
