Hello, We started with two 800GB SSD on each cassandra node based on our initial estimations of read/write rate. As we started on boarding additional traffic we find that CPU is becoming a bottleneck and we are not able to run the NICE jobs like compaction very well. We have started expanding the cluster and this would lead to less data per node. It looks like at this point once we expand the cluster, the current 2 X 800 GB SSD will be too much and it might be better to have just one SSD.
To accomplish this can I just copy the data from disk1 to disk2 with in the relevant cassandra home location folders, change the cassanda.yaml configuration and restart the node. before starting i will shutdown the cluster. Thanks anishek
