I had actually meant to (and thought I did) type "greater than zero and less
than *or equal* to number of nodes".
That being said, you usually do want it less than the number of nodes in the
cluster because otherwise your cluster essentially has the same performance
as a single node. In general (
He probably meant in production. When playing around, and if you only have 2 nodes, you can set it to 2. From memory RF of 2 means the Quorum is also 2, so you cannot afford to lose one. Thats fine for playing. Aaron On 15 Feb, 2011,at 01:51 PM, mcasandra wrote:

In earlier post same thread you mentioned that replication factor should be
set to less than N.
Currently I am testing on 2 node cluster and I was able to set
replication_factor to 2 (=N) and also when I did cfstats (I don't quite
understand cfstats in detail) and see some activity on both nodes

For now, I have committed a change in the misleading documentation,
substituting SimpleStrategy for NTS.
Sorry you ran into trouble due to that, mcasandra.

Will take a closer look at the code tonight, perhaps we should return an error if you try to using Network Topology it cannot detect any DC's . CheersAaron On 15 Feb, 2011,at 01:22 PM, mcasandra wrote:

That's what I thought might be happening since network topology will try to
find one node on the other data center. Message is little confusing though.

Not sure why the docs suggest to use the NetworkTopologyStrategy, if their are no data centres configured the NetworkTopologyStrategy will say the replication factor is 0. I think this is the source of the "invalid response count 1 for replication factor 0" message. Can you try with the SimpleStra
No it's not set to 0. I am just following the example on datastax getting
started site. Here are all the commands:
[default@unknown] create keyspace twissandra with replication_factor=1
... and

Is your ReplicationFactor (RF) really set to 0? Don't do that, it needs to
be at least 1 and probably needs to be 3 in production if you care about
your data. It must be greater than 0 and less than the number of nodes in
your ring. It represents the number of nodes to copy/replicate data to.
