Hi,
We are using Cassandra 3.0.13
We have the following datacenters:
- DC1 with 7 Cassandra nodes with RF:3 (2 years old)
- DC2 with 1 Cassandra node with RF:1 (4 years old)
- DC3 with 2 Cassandra nodes with RF:2 (one-month-old)
On DC2 and DC3, each node has 100% data.
Seed nodes while setting up new-datacenter DC3 were:
- 1 DC2 node
- 1 DC1 node
We are planning to remove the 4-year-old data center (DC2).
We are seeing a discrepancy (around ~250GB) in the load of the nodes in DC2
and DC3 via the "nodetool status" command.

What could be the possible reasons for the 250gb data discrepancy?
Also, we run a repair on every weekend.
Thank you!
