Cassandra nodes are not equal
We have two nodes. Node1 was down for a long time. During this time Node2 raised 1 TB capacity when Node1 has 100 GB.
We tried to repair Node1 with nodetool repair but nothing changed. After that we started nodetool repair in Node2, it took 5 days to compaction but nothing changed either.
Actual status here:
Datacenter: dc1
===============
Status=Up/Down
|/ State=Normal/Leaving/Joining/Moving
-- Address Load Tokens Owns (effective) Host ID Rack
UN 172.x.y.z 149.46 GB 256 100.0% xxx rack1
UN 172.x.y.k 1.04 TB 256 100.0% xyz rack1
Nodes are in AWS. What should we do?

What replication factor are you using?

@ChristopheSchmitz cqlsh:5.0.1 cassandra: 3.0.9 CQL Spec: 3.4.0, Replication factor = 2

Are you doing any delete queries? Are you using TTL?
– Christophe Schmitz
Mar 28 '18 at 7:42
@ChristopheSchmitz We have never done delete queries yet and we are not using TTL. We only use store data and do some backward processing jobs.

We had a solution but don't know how it happened. Here what we did:
- Took snapshot of both servers in case of data loss over AWS
- We detached Volume where data is stored. (for instance 172.x.y.k)
- We formatted instance and loaded Cassandra with new version. Then we
attached Volume where data is stored. - Finally we started
nodetool repair --fullin terminal and it took 4
days.
Now our nodes are equal.
