Red Hat Bugzilla – 1856906 – [RHOSP 13 to 16.1 Upgrades] [OVS to OVN] "ovn_migration.sh start-migration" is failing as soon ansible tasks "Check Keystone public endpoint status" is getting started.
[RHOSP 13 to 16.1 Upgrades] [OVS to OVN] "ovn_migration.sh start-migration" is failing as soon ansible tasks "Check Keystone public endpoint status" is getting started.
The problem doesn't sound like a networking-ovn problem, rather something bad happened during 13 -> 16.1 migration with keystone. This is outside of Networking DFG.
This is actually an issue with cinder's keystone catalog entries. Until a fix is available, try this workaround:
1. Run "openstack endpoint list --service cinderv3" to locate the stale "volume" service endpoints
You should see two sets of entries, one for the "volume3" service (good!) and one set for the obsolete "volume" service (cinder's API V1 was deleted long ago).
2. Run "openstack endpoint delete <ID>" to delete each of the stale "volume" endpoints
3. Run "openstack service list" to locate the "volume" service
4. Run "openstack service delete <ID>" to delete the obsolete "volume" service
