Description
See https://bugzilla.redhat.com/show_bug.cgi?id=1633221
It's rare, but some clusters have pools with very differently-sized objects. "If the amount of data is matching and the object count isn't for different pools, we either need the warning to be more useful, like how it will negatively affect the cluster performance or everything's good to keep as it is" and so the warning shouldn't trigger.
I'm not sure if the best strategy is to check the total data and silence the warning per-pool if the total data is the same, or if we should just warn based on total data amounts rather than object counts, or what, but this warning should be made more careful.
