A node will only request data from other nodes on start up if it is bootstrapping. Bootstrapping happens when there is no system data and the auto_bootstrap: yaml config is set true, normally nodes only bootstrap once in their life.
If you bring a node back for whatever reason you will want too run repair, see also http://wiki.apache.org/cassandra/Operations#Replacing_a_Dead_Node Cheers ----------------- Aaron Morton Freelance Developer @aaronmorton http://www.thelastpickle.com On 21/12/2011, at 10:13 AM, Carlos Pérez Miguel wrote: > What happens with the data stored for that token range already in the > cluster? will the restarted node actualize it from any of the > replicas? > > I readed in the maillist archives that in case of token collision, the > cluster may not work correctly.
