Owns is how much of the entire, cluster wide, data set the node has. In both
your examples every node has a full copy of the data.
If you have 6 nodes and RF 3 they would have 50%.

When RF=N, effective ownership for each node is 100%.

There was a thread on this a couple days ago -- short answer, the 'owns %'
column is effectively incorrect when you're using multiple DCs. If you had
all 3 servers in 1 DC, since server YYY has token 1 and server XXX has token
0, then server XXX would truly 'own' 0% (actually, 1/(2^128) :)

nodetool ring is, IMHO, quite confusing in the case of multiple datacenters.
Might be easier to think of it as two rings:
in your DC1 ring you have two nodes, and since the tokens are balanced,
assuming your rows are randomly distributed you'll have half the data on each,

Thanks David, for the clarification.
I feel it would be better if nodetool ring reports per-dc token space
ownerships to correctly reflect what cassandra is internally doing, instead
of global token space ownership.

does not show me all the nodes in the cluster. It always keeps showing
only one node and mentions that it is handling 100% of the load. But
when I look at the logs, the nodes are able to talk to each other via
the gossip protocol. Why does
that was on a different cassandra
cluster (3 node with RF= 3) to a new cluster. I have a 3 node cluster
with replication factor set to three. When I run nodetool ring, it
does not show me all the nodes in the cluster. It always keeps showing
only one node and mentions that it is handling 100
is present in ring, it doesn't agree RF=3 it is
expecting RF=1.
Original Q: I m not exactly sure what is the problem. But
Does nodetool ring show all the host?
What is your seed list?
Is bootstrapped node has seed ip of its own?
AFAIK gossip work even without actively joining a ring.

not hav to migrate data from any particular
node.
My problem here is why does n't nodetool ring show me all nodes in the
ring ? I agree that the cluster thinks that only one node is present.
How do I fix this ?
Thanks,

Using localhost(or own IP address for non-seed nodes) is not a good
practice.
Try
The seedlist of A : A_ipaddr.
Seedlist of B : A_ipaddr
seedlist of C : A_ipaddr
of A : A_ipaddr.
Seedlist of B : A_ipaddr
seedlist of C : A_ipaddr
That does not work either. Once and do the above and invoke nodetool
ring, it still shows only one node.

I have autobootstrap set to false for all 3 nodes since they all have
the correct data and do not hav to migrate data from any particular
node.

I corrected the seed list and checked the cluster name. They are all
good now. But still nodetool -ring shows only one node.

Nodes a_ipadrr and b_ipaddr have
the first one
(called A).
2 - Delete their LocationInfo CF
3 - ensure the seed list for ALL nodes points to node A.
4 - ensure the initial token is set correctly for B and C
5 - start B and C one at a time and make sure nodetool ring and describe
cluster; in the CLI agree before starting
Just to close this out, in case anyone was interested... my problem was
firewall related, in that I didn't have my messaging/data port (7000) open
on my seed node. Allowing traffic on this port resolved my issues.

I have 3 cassandra 0.7.4 nodes in a cluster, and I get the ring stats:

This is normal when you just add single nodes. When no token is assigned,
the new node takes a portion of the ring from the most heavily loaded node.
As a consequence of this, the nodes will be out of balance.
In other words, when you double the amount nodes you would not have this
The 3 nodes were added to the cluster at the same time, so I'm not sure whey
the data vary.
I calculate the tokens and get:
node 0: 0
node 1: 56713727820156410577229101238628035242
node 2: 113427455640312821154458202477256070485
So I should set these tokens to the three nodes?
