Didn't notice the racks! Of course....
The main issue is that one of your us-east nodes is in rack 1d, while the restart are in rack 1c. With NTS and multiple racks, Cassandra will try use one node from each rack as a replica for a range until it either meets the RF for the DC, or runs out of racks, in which case it just picks nodes sequentially going clockwise around the ring (starting from the range being considered, not the last node that was chosen as a replica).
To fix this, you'll either need to make the 1d node a 1c node, or make 42535295865117307932921825928971026432 a 1d node so that you're alternating racks within that DC.--

Hi,I recently upgraded from 0.8.x to 1.1.x (through 1.0 briefly) and nodetool -ring seems to have changed from "owns" to "effectively owns". "Effectively owns" seems to account for replication factor (RF). I'm ok with all of this, yet I still can't figure out what's up with my cluster. I have a NetworkTopologyStrategy with two data centers (DCs) with RF/number nodes in DC combinations of:DC Name, RF, # in DCanalytics, 1, 2us-east, 3, 4So I'd expect 50% on each analytics node, and 75% for each us-east node. Instead, I have two nodes in us-east with 50/100??? (the other two are 75/75 as expected).Here is the output of nodetool (all nodes report the same thing):Address DC Rack Status State Load Effective-Ownership Token127605887595351923798765477786913079296x.x.x.x us-east 1c Up Normal 94.57 GB 75.00% 0x.x.x.x analytics 1c Up Normal 60.64 GB 50.00% 1x.x.x.x us-east 1c Up Normal 131.76 GB 75.00% 42535295865117307932921825928971026432x.x.x.x us-east 1c Up Normal 43.45 GB 50.00% 85070591730234615865843651857942052864x.x.x.x analytics 1d Up Normal 60.88 GB 50.00% 85070591730234615865843651857942052865x.x.x.x us-east 1d Up Normal 98.56 GB 100.00% 127605887595351923798765477786913079296If I use cassandra-cli to do "show keyspaces;" I get (and again, all nodes report the same thing):Keyspace: civicscience:Replication Strategy: org.apache.cassandra.locator.NetworkTopologyStrategyDurable Writes: trueOptions: [analytics:1, us-east:3]I removed the output about all of my column families (CFs), hopefully that doesn't matter.Did I compute the tokens wrong? Is there a combination of nodetool commands I can run to migrate the data around to rebalance to 75/75/75/75? I routinely run repair already. And as the release notes required, I ran upgradesstables during the upgrade process.Before the upgrade, I was getting analytics = 0%, and us-east = 25% on each node, which I expected for "owns".will
