Subject Re: Restarting cluster

Normally, no.  What you've done is fine.  What is the environment?

On amazon EC2 for example, the instance could have crashed, a new one
is brought online and has a different internal IP ...

in the cassandra/logs/system.log are there any messages on the 2nd
node and how it relates to the seed node?
