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:

https://logs.opendaylight.org/releng/vex-yul-odl-jenkins-1/netvirt-csit-1node-openstack-queens-gate-stateful-fluorine/243/robot-plugin/log_01_l2.html.gz#s1-t1-k4-k2-k1-k1

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
