Subject Re: Equalizing nodes storage load
Date Fri, 22 Jul 2011 21:00:09 GMT
I'm not sure if this is the answer, but major compaction on each node
for each column family. I suspect the data shuffle has left quite a few
deleted keys which may get cleaned out on major compaction. As I
remember major compaction doesn't automatically in 7.x, I'm not sure if
it is triggered by repair.

2^127 / num_nodes.  The only reason the first one doesn't start at 0 is that I''ve actually
carved the ring planning for 9 machines (2 new data centers of 3 machines each).  However
only 1 data center (DCMTL) is currently up.
