> Hi,

fine nodetool status show 2 node status up for each cluster.
> Then I have taken backup of Cassandra first cluster of 2 nodes and restored it to  second
2 nodes cluster.   nodetool status got messed up now it is showing all 4 nodes as part of
cluster on each nodes of both cluster.
>  I tried to debug this issue but not able to come up to solution. Please note that both
cassandra clusters are running terremark ecloud. Is this SAN issue for node mess up????
> Then i found both cluster have same name in the cassandra.yaml. Then i changed the cluster
name of second cluster. After that restore is not working both cassandra nodes are not coming
up. they are throwing following error:-
