> We currently allow reducing scope (removing sstables from the compaction) 
> when starting STCS-in-L0 with LCS if the compaction is too large for the 
> available disk space. We can do the same for L0 -> L1 compactions - but we 
> can only remove L0 sstables to avoid causing overlap in L1.
> Also, in 3.0, when starting an LCS compaction we try to [get a writeable 
> location|https://github.com/apache/cassandra/blob/b1a8a56c563b85ab9a34d3bbf9c16278dd441157/src/java/org/apache/cassandra/db/compaction/writers/CompactionAwareWriter.java#L128]

> directory where the first sstable fits, otherwise the compaction might fail 
> even though there is enough space in total among the data directories
