shows the multipath delete rule. I am on 32 and don't see anything else using it.
if you cat the rule with the del_part_nodes code you could see if anything else on 33 uses it.
del_part_nodes appears only in /lib/udev/rules.d/68-del-part-nodes.rules which has at the start:
# To suppress this, use the kernel parameter "dont_del_part_nodes", # or create an udev rule file that sets ENV{DONT_DEL_PART_NODES}="1".
As I cannot change the kernel par, I added a (found online) /lib/udev/rules.d/00-dont-del-part-nodes.rules with
SUBSYSTEM=="block", KERNEL=="sd*|dasd*|rbd*", ACTION=="add|change", \ ENV{DONT_DEL_PART_NODES}="1"
and rebooted but nothing changed.
