Description of problem: During the upgrade process from RHCS 6.1 to 8.0, the rgw_run_sync_thread configuration parameter is incorrectly reset to true even when it was explicitly set to false before the upgrade. This behavior is not observed when upgrading from RHCS 6.1 to 7.1, where the parameter retains its original value. Version-Release number of selected component (if applicable): ceph version 19.1.0-50.el9cp How reproducible: Always Steps to Reproduce: 1. Set up an RHCS environment with version 6.1 with multiple rgw daemons. 2. Set the rgw_run_sync_thread parameter to false for a few rgw daemons that would not participate in sync. 3. Perform an upgrade from RHCS 6.1 to 7.1 in the primary zone. 4. Verify that the rgw_run_sync_thread parameter remains false for the rgws that had it set as 'false' after the upgrade. 5. Perform an upgrade from RHCS 6.1 to 8.0 in the secondary zone. 6. Check the value of rgw_run_sync_thread using ceph config show | grep sync_thread. Actual results: Upgrade from Ceph 6.1 to 7.1: The rgw_run_sync_thread parameter remains false as expected. Upgrade from Ceph 6.1 to 8.0: The rgw_run_sync_thread parameter is reset to true, which is not expected behavior. Expected results: The rgw_run_sync_thread parameter should retain its pre-upgrade value of false after any upgrade, including to RHCS 8.0. Additional info: Impact: This bug could potentially cause unintended behavior in the RGW Multisite clusters where the sync thread should remain disabled. Users upgrading to RHCS 8.0 might experience issues related to unnecessary sync operations if they rely on this setting being false.
