East and West Clusters have been upgraded to quincy, 17.2.6.
We are still seeing replication failures. Deep diving the logs, I found the following interesting items.
What is the best way to continue to troubleshoot this?
What is the curl attempting to fetch, but failing to obtain?

no object data would be deleted as a result of metadata failover issues, no

does the multisite system user exist on the rgw-west zone? you can
check there with `radosgw-admin user info --access-key
PxxxxxxxxxxxxxxW`
the sync status on rgw-west shows that metadata sync is caught up so i
would expect it to have that user metadata, but maybe not?
