Your us-east datacenter, has RF=2, and 2 racks, which is the right way to do it (I would rarely recommend using a different number of racks than your RF). But by having three nodes on one rack (1b) and only one on the other(1a), you are telling Cassandra to distribute the data so that no two copies of the same partition exist on the same rack.
So with rack ownership of 100% and 100% respectively, there is no even way to distribute your data among those four nodes. tl;dr Switch node 2 to rack 1a. -Tupshin On Mon, Apr 7, 2014 at 8:08 AM, Oleg Dulin <oleg.du...@gmail.com> wrote: > I added two more nodes on Friday, and moved tokens around. > > For four nodes, the tokesn should be: > > Node #1: 0 > Node #2: 42535295865117307932921825928971026432 > Node #3: 85070591730234615865843651857942052864 > Node #4: 127605887595351923798765477786913079296 > > And yet my ring status shows this (for a specific keyspace).
