Is 0 really OK? I remember some bugs coming up recently with a token of 0. I was thinking about moving my 0 token servers to 1 because of that.

Patrick, if you try adding capacity again from the beginning, I'd be curious to hear if the DataStax/Riptano <http://www.datastax.com/docs/0.7/operations/clustering#adding-capacity> docs are helpful or not. Also, in the Getting Started page <http://www.datastax.com/docs/0.7/getting_started/index> , we note that it may be best to set initial_token to 0 on the very first node that you start.

I don't see that you did anything wrong based on your description and based on my understanding how it works in 0.7 (not sure about 0.6), but hopefully someone else can address that part. What I can think of - did you inspect the log on the new node? Does it say anything about bootstraping or streaming data from other nodes? Does 'nodetool ring' indicate it considers itself completely up and in the cluster already? Trying to determine whether the node is in fact considering it self done bootstrapping and joined to the ring, yet containing no data. > I tried then to put values for initialToken for both nodes (stopping and > restartings the servers), but it didn't change anything : I have the same > token values... This is expected. Once the node has bootstrapped into the cluster and saved its token, it will no longer try to acquire a new one. Any initial token in the configuration is ignored; it is only the *initial* token, quite literally. Changing the token would require a 'nodetool move' command. -- / Peter Schuller -- Eric Gilmore Consulting Technical Writer Riptano, Inc. Ph: 510 684 9786 (cell)
