Normal Description
I'm trying to run cleanup, but get this:
INFO [CompactionExecutor:18] 2015-03-25 10:29:16,355 CompactionManager.java (line 564) Cleaning up SSTableReader(path='/cassandra/production/Data_daily/production-Data_daily-jb-4345750-Data.db')

Now that's odd, since:
- Disk has some 680G left
- The sstable it's trying to cleanup is far less than 680G:
# ls -lh *4345750* -rw-r--r-- 1 cassandra cassandra 64M Mar 21 04:42 production-Data_daily-jb-4345750-CompressionInfo.db -rw-r--r-- 1 cassandra cassandra 219G Mar 21 04:42 production-Data_daily-jb-4345750-Data.db -rw-r--r-- 1 cassandra cassandra 503M Mar 21 04:42 production-Data_daily-jb-4345750-Filter.db -rw-r--r-- 1 cassandra cassandra 42G Mar 21 04:42 production-Data_daily-jb-4345750-Index.db -rw-r--r-- 1 cassandra cassandra 5.9K Mar 21 04:42 production-Data_daily-jb-4345750-Statistics.db -rw-r--r-- 1 cassandra cassandra 81M Mar 21 04:42 production-Data_daily-jb-4345750-Summary.db -rw-r--r-- 1 cassandra cassandra 79 Mar 21 04:42 production-Data_daily-jb-4345750-TOC.txt
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?
