Description Itzik Brown 2018-04-03 09:31:42 UTC 
Description of problem:
After restart of a compute node that holds the NAPT switch the router is not migrated and it has a null Managment Ip Address when running the display-napt-switches.
Seen on bare metal setup non-HA.

Version-Release number of selected component (if applicable):
opendaylight-8.0.0-5.el7ost.noarch

How reproducible:


Steps to Reproduce:
1.Create a router and add the gateway info.
2.Run display-napt-switches to show the node that holds the NAPT switch
3.Reboot the node
4.Run display-napt-switches and verify the Managment Ip Address is null for this router.

Actual results:


Expected results:

This seems to work on a virt setup so it should work regardless.
If you see this again please re-open.
Comment 4 Itzik Brown 2018-04-16 16:09:24 UTC 
I'm now facing a similar issue on a virt HA setup.
After creating multiple routers one of them has a null management IP

Comment 6 Vishal Thapar 2018-04-24 09:40:13 UTC 
Require ODL karaf logs and Datastore dumps. Datastore dumps can be acquired by making simple curl calls to URLs as captured in:

Also:
<wznoinsk> vthapar, itzikb can you try running http://file.tlv.redhat.com/~wznoinsk/overcloud_capture.sh on an undercloud? (it should capture ovs data, datastore data, sosreports)
Comment 7 Vishal Thapar 2018-04-25 14:59:26 UTC 
wznoinsk's script will capture all the datastore dumps.
Comment 12 Itzik Brown 2018-05-21 14:02:15 UTC 
Don't see it with:
opendaylight-8.0.0-10.el7ost.noarch
