Hi, We have a Cassandra 3.0.8 cluster (recently upgraded from 2.1.15) currently running in two data centers (13 and 19 nodes, RF3 in both). We are adding a third data center before decommissioning one of the earlier ones. Installing Cassandra (3.0.8) goes fine and all the nodes join the cluster (not set to bootstrap, as documented in https://docs.datastax.com/en/cassandra/3.0/cassandra/operations/opsAddDCToCluster.html ).
When trying to rebuild nodes in the new DC from a previous DC (nodetool rebuild -- DC1), we get the following error: Unable to find sufficient sources for streaming range (597769692463489739,597931451954862346] in keyspace system_distributed The same error occurs which ever of the 2 existing DCs we try to rebuild from. We run pr repairs (nodetool repair -pr) on all nodes twice a week via cron. Any advice on how to get the rebuild started? Best regards, Timo
