After rebooting a node, which is a single node running OVN, at one of of an OVN-IC link, the OVN network now fails to start. The logs are showing;
DEBUG [2025-06-19T12:58:35Z] OVN router external IP address unreachable \
driver=ovn err="Failed to run: ping -n -q 10.0.0.240 -c 1 -w 1: exit status 1" \
ip=10.0.0.240 network=private project=default
Something has clearly changed but I’ve no idea what. My deployment code says the install is the same as it was when it was installed and worked. There appear to be no other errors and as far as I can see from the logs everything else is working. I’ve spent 3-4 hours now trying to debug this, if anyone has an ideas what might be causing this I’m all ears as I’m about out of ideas.
Without some logging pointing at a problem I just don’t know where to look …
