Description
Hello All,
I have single datacenter with 3 C* nodes and we are trying to expand the cluster to another region/DC. I am seeing the below error while doing a "nodetool rebuild – name_of_existing_data_center" .
[user@machine ~]$ nodetool rebuild DC1 nodetool: Unable to find sufficient sources for streaming range (-402178150752044282,-396707578307430827] in keyspace system_distributed See 'nodetool help' or 'nodetool help <command>'. [user@machine ~]$
user@cqlsh> SELECT * from system_schema.keyspaces where keyspace_name='system_distributed'; keyspace_name | durable_writes | replication ---------------+----------------+------------------------------------------------------------------------------------- system_distributed | True | {'class': 'org.apache.cassandra.locator.SimpleStrategy', 'replication_factor': '3'} (1 rows)
To overcome this I have updated system_distributed keyspace to DC1:3 and DC2:3 with NetworkTopologyStrategy
C* Version - 3.0.8
Is this a bug that is introduced in 3.0.8 version of cassandra? as I haven't seen this issue with the older versions?
