I have the cassandra 4.0.1 cluster with 3 nodes (datacenter1) and we have decided that we need to add the second datacenter (datacenter2), I have done all the steps described in this article
First of all, we have added the nodes one by one with the
auto_bootstrap: false option in the
cassandra.yaml configuration for all three new nodes.
The replication factor was
rf=o for datacenter2 during adding/bootstraping process.
Then we have changed from
rf=3 for system_auth, system_traces, system_distributed keyspaces and my user keyspace which is named big_data for datacenter2 through
All the nodes have joined to cluster successfully, but there is one strange situation there:
We cannot do the rebuild process from datacenter1 and cassandra tells me the following:
nodetool: Unable to find sufficient sources for streaming range Full(/192.168.1.141:7000,(9143760283360780305,-9086318401025854203]) in keyspace system_auth
...and I saw the same print on the next new nodes. What can I do with it?
Schema version is the same on all nodes.
If I perform full repair all the data will appear on all new nodes, but the rebuild process still doesn't work properly in this case.
I need your advice.
