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 DC
analytics, 1, 2
us-east, 3, 4
So 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):

If 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.NetworkTopologyStrategy
Durable Writes: true
Options: [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".
