Recovering from a degraded state by copying existing replicas to other OSDs is going to cause reads on existing replicas and writes to the new locations. If you have slow media then this is going to be felt more acutely. Tuning the backfill options I posted is one way to lessen the impact, another option is to slowly lower the weight in CRUSH for the OSD(s) you want to remove. Hopefully that helps!
