Description Tridibesh Chakraborty 2023-03-21 17:57:07 UTC 
Description of problem:
When customer is upgrading their RGW multisite cluster, they are experiencing the sync is getting broken between the sites when one site is upgraded and another one is still pending

Version-Release number of selected component (if applicable):
RHCS 5.3.1 (16.2.10-138.el8cp)
RHCS 4.3.1 (14.2.22-128.el8cp)

How reproducible:
It is happening all the time

Steps to Reproduce:
1. Install 2 RHCS 4 cluster
2. Setup RGW multisite between them
3. Create some buckets and upload objects into the buckets
4. Wait for the sync to complete
5. Now upgrade one site from RHCS 4.3.1 to RHCS 5.3.1
6. Create a new bucket on the RHCS 4 site and upload objects into the bucket
7. Check the bucket and its content from the RHCS 5 site, they are missing there
8. If we create buckets on RHCS 5 site and upload objects there, it is getting replicated


Actual results:
During upgrade the sync is getting broken

Expected results:
RGW multisite sync should not get impacted

Additional info:

Multiple customers faced the similar issue and once they update the other site also, the sync was restored
