Summary: DS Cassandra3.0 Adding a datacenter to a cluster procedure not working for us Key: CASSANDRA-13378 URL: https://issues.apache.org/jira/browse/CASSANDRA-13378 Project: Cassandra Issue Type: Bug Components: Configuration Environment: 5 node cluster , • Server Model: Dell R730xd • Processor: 2 * Intel Xeon E5-2630 – Total 16 cores • Memory: 192 GB • OS Drive: 2 * 120 GB • Direct attached storage – 8 TB (4 * 2TB SSD) + 1 * 800GB SSD • 10Gb Dual Port + 1Gb Dual Port Network Daughter Card OS - OEL 2.6.32-642.15.1.el6.x86_64 java version "1.8.0_91" Java(TM) SE Runtime Environment (build 1.8.0_91-b14) Java HotSpot(TM) 64-Bit Server VM (build 25.91-b14, mixed mode) 6 nodes in other DC are identical Reporter: Kevin Rivait Priority: Blocker Fix For: 3.0.9 Attachments: cassandra.yaml, DS-add-a-dc-C3.0.rtf i have replicated the issue on my personal cluster using VMs. we have many keyspaces and users developing on the Dev Cluster we are trying to stretch. With my current VMs (10 total) i can create a 2 DC cluster dc1 and dc2. i rebuild all nodes - clear data dirs and restart dc1. i also clear data dirs on dc2 nodes, i donot restart yet, now i have single dc1 5 nodes cluster. snitch - GossipingPropertyFileSnitch i create keyspaces on DC1 after i alter keyspaces with replication dc1 3 dc2 0 i can no longer query tables - not enough replicas available for query at consistency ONE. same error with CQL using consistency local_one continue with procedure, startup dc2 nodes, alter replication on keyspaces to dc1 3 dc2 2 from dc2 nodes , nodetool rebuild -- dc1 fails i am attaching detailed steps with errors and cassandra.yaml -- This message was sent by Atlassian JIRA (v6.3.15#6346)
