Hi! I am re-posting this, now that I have more data and still *unbalanced ring*:
3 nodes, RF=3, RCL=WCL=QUORUM Address DC Rack Status State Load Owns Token 113427455640312821154458202477256070485 x.x.x.x us-east 1c Up Normal 24.02 GB 33.33% 0 y.y.y.y us-east 1c Up Normal 33.45 GB 33.33% 56713727820156410577229101238628035242 z.z.z.z us-east 1c Up Normal 29.85 GB 33.33% 113427455640312821154458202477256070485 repair runs weekly. I don't run nodetool compact as I read that this may cause the minor regular compactions not to run and then I will have to run compact manually. Is that right? Any idea if this means something wrong, and if so, how to solve?
