If you have a replication of 3 and only one OSD was involved, what is stopping you from taking that wonky drive/OSD out? If you don't know that or want to play it safe, how about setting the weight of that OSD to 0? While that will AFAICT still result in all primary PGs to be evacuated off it, no more writes will happen to it and reads might be faster. In either case, it shouldn't slow down the rest of your cluster anymore.
