----------------------------------------
Summary: "disk full" when running cleanup (on a far from full disk)
Key: CASSANDRA-9036
URL: https://issues.apache.org/jira/browse/CASSANDRA-9036
Project: Cassandra
Issue Type: Bug
Reporter: Erik Forsberg
I'm trying to run cleanup, but get this:
{noformat}
INFO [CompactionExecutor:18] 2015-03-25 10:29:16,355 CompactionManager.java

Now that's odd, since:
* Disk has some 680G left
* The sstable it's trying to cleanup is far less than 680G:

Sure, it's large, but it's not 680G.
No other compactions are running on that server. I'm getting this on 12 / 56
servers right now.
Could it be some bug in the calculation of the expected size of the new
sstable, perhaps?
