Description Mike Hackett 2019-08-15 19:22:41 UTC

Description of problem:
In RHCS 3 we ONLY support using the upmap feature with the ceph-mgr balancer module for automated resolution of PG imbalance issues. It is not tested or supported without using the balancer module for manual data migration purposes. 

We need to document this:
