nodetool reports much higher load than actual?

I have a ring with 24 nodes, in 2 datacenters. Each node is using Apache Cassandra 2.2.10, and all work generally OK.

But I am seeing HUGE discrepancy between disk space usage and Load as reported by nodetool.

On one of the nodes, I see:

=$ nodetool info | grep Load
Load                   : 1.99 TB

while the data directory is only:

=$ sudo du -sh /var/lib/cassandra/data/
331G    /var/lib/cassandra/data/

There are some snapshots in there, but from what I understand, they can increase data usage on disk, but shouldn't increase Load. Which would make sense if load would show 100, and disk space would be 300. But for me - Load is 6 times more than actual disk space usage.

I do not use disk compression, and even checking file sizes as reported by ls - I'm getting ~ 330G on disk.

What am I missing? Why is Load so high?

Its most likely from a a bug (CASSANDRA-13738) that was fixed in 2.2.11.
