> 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
