With multiple data dirs you are still limited by the space free on any
one drive.  So if you have two data dirs with 40GB free on each, and you
have 50GB to be compacted, it won't work, but if you had a raid, you
would have 80GB free and could compact...

How does compaction work in terms of utilizing multiple data dirs? Also,
is there a reference on wiki somewhere that says not to use multiple
data dirs?
