Hi, we have seen similar issues here.
have you verified that your rebuilds have been finished successfully? we have seen rebuilds that stopped streaming and working but have not finished. what does nodetool netstats output for your newly built up nodes? br, roland On Mon, 2017-04-10 at 17:15 +0200, George Sigletos wrote: Hello, We recently added a new datacenter to our cluster and run "nodetool rebuild -- <DC_current>" in all 5 new nodes, one by one. After this process finished we noticed there is data missing from the new datacenter, although it exists on the current one. How would that be possible? Should I maybe have run repair in all nodes of the current DC before adding the new one? Running Cassandra 2.1.15 Kind regards, George
