Sounds like you have done some solid test work.

I suggest reading https://issues.apache.org/jira/browse/CASSANDRA-6568 and if you think your issue is the same adding your reproduction case there, otherwise create your own ticket.

Yeah, it's definitely repeatable. I have a lab environment set up where the
issue is occurring and I've recreated the lab environment 4 - 5 times and
it's occurred each time.

In my demodb.users CF I currently have 2 data SSTables on disk
(demodb-users-jb-1-Data.db and demodb-users-jb-6-Data.db). However, in
OpsCenter the CF: SSTable Count (demodb.users) graph shows only one SSTable.

The nodetool cfstats command also shows "SSTable count: 1" for this CF.

I'm running C* 2.0.4 and when I have a handful of SSTable files and

Is there something special about the first SSTable that it remains even
after a SizedTierCompaction?



No, this is not expected behavior.  Do the number of live SSTables
reported match what is on disk?  Do you have a procedure that can repeat
this?
