Hi, Same thing here:
2 nodes, RF = 2. RCL = 1, WCL = 1. Like Tamar I never ran a major compaction and repair once a week each node. 10.59.21.241 eu-west 1b Up Normal 133.02 GB 50.00% 0 10.58.83.109 eu-west 1b Up Normal 98.12 GB 50.00% 85070591730234615865843651857942052864 What phenomena could explain the result above ? By the way, I have copy the data and import it in a one node dev cluster. There I have run a major compaction and the size of my data has been significantly reduced (to about 32 GB instead of 133 GB). How is that possible ? Do you think that if I run major compaction in both nodes it will balance the load evenly ? Should I run major compaction in production ? 2012/10/10 Tamar Fraenkel <ta...@tok-media.com> > 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.
