Description of problem:
After attempting a couple of OpenShift installations with and without Kuryr as SDN in parallel, we started noticing that Networks were first not allowed to get created, then that Routers external gateway were not allowed to be set. After checking the ovn-controller logs it was noticed that the following warning was constantly triggered:
2021-09-10T14:21:46.314Z|104284|ovsdb_idl|WARN|transaction error: {"details":"Transaction causes multiple rows in \"MAC_Binding\" table to have identical values (lrp-5929ab56-6070-46c7-9700-bc9fb91e636e and \"38.x.x.x\") for index on columns \"logical_port\" and \"ip\". First row, with UUID c20de7f7-b5ad-4a1d-bfc0-864eba110aeb, existed in the database before this transaction and was not modified by the transaction. Second row, with UUID ce8406ab-f425-411c-a39d-a377f71460ed, was inserted by this transaction.","error":"constraint violation"}
We have attempted setting neutron_sync_mode=repair to fix it, but it was eventually happening again.
There was a discussion[0] on the mailing list reporting similar issues, but as the workaround[1] is enforced (we were using tripleo master) I assume these warnings might be caused by some other corner case.
