Description of problem: In upstream Ceph we have found that async data notifications solve sync consistency problems. In downstream Ceph this seemed to have no effect or made it worse. We recently discovered a patch that was originally introduced as part of the testing framework is required to make disabling async data notifications possible. Without it, attempting to disable them just resulted in more of them being sent more frequently. Version-Release number of selected component (if applicable): All 4.x and 5.x How reproducible: Deterministically. Steps to Reproduce: 1. Set up a multisite cluster 2. Set rgw_data_notify_interval_msec to 0 3. Ingest data into it Actual results: No async data notifications. At level 20, the log does not show 'notifying datalog change' entries Expected results: Oh so many async data notifications. At level 20, the log DOES show 'notifying datalog change' Additional info: As async data log notifications may be the ultimate root of sync inconsistency errors we've been seeing, this needs to be fixed so we can test disabling them properly.
