I bet the culprit is how LCS sets the min/max compaction threshold but STCS does not.  Can you try the attached patch?

> When column family compaction strategy is changed from Leveled to SizeTiered and there're Leveled compaction tasks pending, Cassandra starting to flood in logs with thousands per sec messages:
> Nothing to compact in ColumnFamily1.  Use forceUserDefinedCompaction if you wish to force compaction of single sstables (e.g. for tombstone collection)
> As a result, log disk is full and system is down.
