I noticed that even ports don't clean from ovn DB

You mean that after creating a network and some ports with openstack (not ovn-nbctl) and then deleting them would not clean the resources from the backend (OVN)?

Could you please post some reproduction steps? I have tried simple commands and it appears to work:


$ openstack network create test_net

$ openstack network delete 44aa72a2-5413-4f96-8b67-76111230f301

$ sudo ovn-nbctl ls-list | grep 44aa72a2
$

If you could please reproduce it and indicate the steps, it'd be really helpful.
How reproducible is it?

Thanks,
Daniel

Yes, this is exactly what I meant you can see the output from my setup, Numan saw the issue on my setup.
Steps to Reproduce:
1. create few networks  
2. I found it after I restarted ovn northd docker {https://bugzilla.redhat.com/show_bug.cgi?id=1560892}
3. create few instances 10  for example (few of the instances are in error state - lack of resource)
4. remove all instances & network 
%. verify that they removed from ovn-nbctl
I saw that switches &  port  not deleted

I think this is a side effect of https://bugzilla.redhat.com/show_bug.cgi?id=1560892
How reproducible is it?

I saw it twice. 
I will try to reproduce it again on fresh setup deployment.

Could not reproduce this issue. 

You can close this one. I will reopen it if I will see it again
