For more info: http://www.datastax.com/support/tokens
- Run:
sudo mkdir /raid0/cassandra.bak; sudo mv /raid0/cassandra/* /raid0/cassandra.bak

sudo service cassandra start
Runningnodetool -h `hostname` ringwill confirm you're new node is up and running and has joined the existing cluster.
You typically want to double a cluster size and you want to calculate based on the ring you want in the end.
Say you have 3 nodes, but want 6, calculate the tokens for a 6 node cluster. The nodes you currently have are 0, 2, and 4 and you'll be adding 1, 3, and 5.
