Fixed In Version: ceph-18.2.0-1
Doc Type: Bug Fix
Doc Text:
.Multi-site replication now maintains consistent states between zones and prevents overwriting deleted objects Previously, a race condition in multi-site replication would allow objects that should be deleted to be copied back from another site, resulting in an inconsistent state between zones. As a result, the zone which is receiving the workload ends up with some objects which should be deleted still present. With this fix, a custom header is added to pass the destination zone's trace string and is then checked against the object's replication trace. If there is a match, a 304 response is returned, preventing the full sync from overwriting a deleted object.

Description Matt Benjamin (redhat) 2023-07-03 15:31:00 UTC 
Description of problem:

The proposed fix for a race condition in multisite during full sync involving deletes. A custom header was added passing the destination zone's trace string and is then checked against the object's replication trace. If there is a match, a 304 response is returned which will prevent full sync from overwriting a deleted object. Please see the tracker for more details.
