Bug Description


when the overcloud node is rebooted br-ex never comes up, hence the openstack-services don't come up. I tried to do:

NM_CONTROLLED=no ( in all interfaces)

#systemctl disable NetworkManager
#systemctl stop NetworkManager
#chkconfig network on
#service network restart

Then the br-ex comes up but with a different ip from the original (it should get

br-ex: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
        inet netmask broadcast
        inet6 fe80::d6ae:52ff:fea1:cd80 prefixlen 64 scopeid 0x20<link>

Out of curiosity, have you tried running os-collect-config --force --one to see if it's able to get the bridge back up?

no I didn't. I don't have my environment up right now to test it.

Please include your overcloud-env.json (redact secrets if necessary) and the output of 'os-collect-config --force --one'. It will be fairly difficult to reproduce this situation otherwise. I have rebooted controllers quite a few times myself of late, and had no problem like this, but my configuration is likely somewhat different. Also please let us know exactly what OS you're using.. ideally what elements you built the controller image with.
