Good Afternoon,
I am experiencing an issue where east-1 is no longer able to replicate from
west-1, however, after a realm pull, west-1 is now able to replicate from
east-1.
In other words:
West <- Can Replicate <- East
West -> Cannot Replicate -> East
After confirming the access and secret keys are identical on both sides, I
restarted all radosgw services.
Here is the current status of the cluster below.
Thank you for your help,
Eli Tarrago
