> Cassandra has two data directories as follow:
> cassandra-disk0 use about 500G, about 250G free space
> cassandra-disk1 use about 500G, about 250G free space
> The max data file is about 400G. When I upgrade from SizeTieredCompactionStrategy to
LeveledCompactionStrategy, there is no space to do this, for the free space of every data
directory is small than the largest data file. But the total free space is enough for compaction.
