title: How nodetool rebuild works
body: <p>I have cluster of 4 cassandra nodes in aws singapore region (4 cores,32 GB RAM). I need to migrate it to mumbai region so i created a new cluster of 3 nodes in mumbai region and named it as a different datacenter and changed the clients accordingly. I run nodetool rebuild to replicate the data from old datacenter to new datacenter. Data on disk is showing around 150GB but when i run nodetool status is showing only 26 GB. Cassandra version 3.9. The nodetool rebuild is still running.</p>
