Description
OS: ubuntu 20.04 LTS

I had to stop and disable the multipathd service so that i can promote and demote the states as usual.

don't use software that is over 4 years old when you don't want to run into bugs that got fixed over 3 years ago... LINBIT/drbd-utils@7df5687

Great, like i thought need to blacklist it. BTW why there are no update since 9.11 for U20 and 9.15 for U22?

We are upstream here, that is a question for the Ubuntu maintainers when, how, if they update and which issues they fix. most likely this is an issue nobody made them aware of.
We provide up to date software for your customers including all supported Ubuntu LTS releases as part of our support subscription.

Thanks for the clarity, actually it is far worse in 18.04. Thanks again @rck
