[Bug 1940976] Re: Race condition in zone serial generation on concurrent changes to recordsets
@johnsom thanks a bunch for getting back to me. NO I am not using a coordinator. As discussed on IRC, Designate apparently requires a DLM even when running just as a single instance to coordinate multiple updates to a single zone? As I wrote in https://review.opendev.org/c/openstack/designate/+/776173 using the backend storage to synchronize the incrementation of the zone serial does appear to work and would be a nice addition to allow a DEV or otherwise run single instance to not require a DLM. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1940976 Title: Race condition in zone serial generation on concurrent changes to recordsets To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-archive/+bug/1940976/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Yes, that is what I am asking about. The configuration setting: [coordination] backend_url = Such that the threads are using the distributed lock manager.

@johnsom Could you elaborate what I should check for exactly. I tested this while having reduced our set of three designate instances to just one to rule out any side-effects in this regard.
