Hello everyone, Below is our current setup, the master zone is on the master datacenter and the backup zone is on the standby datacenter which has very slow bandwidth internet connection. The client application connects to the Master zone load balancer for uploading objects to cluster. Later on, the Gate way nodes from the Backup zone will synchronize new objects into the Backup cluster by requesting object data to the load balancer of the master zone. [A screenshot of a cell phone Description automatically generated] The current connection inside Gateway nodes of the backup zone [A screenshot of a computer Description automatically generated] From the above image, you can see that the first Gateway node create a lot of connection to the master zone balancer (cephmm-03) for checking objects status. That means this gateway mostly will take the role for downloading new objects from the master zone to the backup zone (very high load on this node). On the other hand, the second Gateway node just has only 2 connections to the master node balancer (mostly free all the time). This second node only increase connections if the first node (or may be the third node) is down… Can you explain this behavior of Ceph in this case and how to let all the gateway node in active mode? I appreciate any comments from you! -- Nghia Viet Tran (Mr)
