Hello All, I am trying to restore a cluster with VNODE(s) to a new cluster using the snapshot. After the restore when I query data from cql I see some random data is missing.
I used the below steps to restore 1. Snapshot on the source cluster 2. Setup new cluster(VNODEs) with the same schema as source cluster. 3. Restore the snapshot to the specific CF directory 4. Restart the node. 5. Now when I query through CQL I see some data is missing. I looked at the procedure documented in : http://docs.datastax.com/en/cassandra/2.1/cassandra/operations/ops_snapshot_restore_new_cluster.html When I try to follow the steps in the above doc, especially replacing the num_tokens with initial_token: from the source cluster token, I get the below error. ERROR [main] 2017-08-30 17:17:20,878 CassandraDaemon.java:395 - Fatal configuration error org.apache.cassandra.exceptions.ConfigurationException: Cannot change the number of tokens from 256 to 1 at org.apache.cassandra.service.StorageService.joinTokenRing(StorageService.java:972) ~[apache-cassandra-2.1.16.jar:2.1.16] at org.apache.cassandra.service.StorageService.initServer(StorageService.java:740) ~[apache-cassandra-2.1.16.jar:2.1.16] at org.apache.cassandra.service.StorageService.initServer(StorageService.java:617) ~[apache-cassandra-2.1.16.jar:2.1.16] at org.apache.cassandra.service.CassandraDaemon.setup(CassandraDaemon.java:391) [apache-cassandra-2.1.16.jar:2.1.16] at org.apache.cassandra.service.CassandraDaemon.activate(CassandraDaemon.java:566) [apache-cassandra-2.1.16.jar:2.1.16] at org.apache.cassandra.service.CassandraDaemon.main(CassandraDaemon.java:655) [apache-cassandra-2.1.16.jar:2.1.16] INFO [StorageServiceShutdownHook] 2017-08-30 17:17:20,898 Gossiper.java:1454 - Announcing shutdown INFO [StorageServiceShutdownHook] 2017-08-30 17:17:22,902 MessagingService.java:734 - Waiting for messaging service to quiesce INFO [ACCEPT-/x <http://10.16.4.182/>.x.x.x] 2017-08-30 17:17:22,903 MessagingService.java:1020 - MessagingService has terminated the accept() thread any pointers on this?
