Subject nodetool repair
Date Thu, 15 Jul 2010 18:54:53 GMT
if i have N=3 and run nodetool repair on node X.  i assume that merkle
trees (at a minimum) are calculated on nodes X, X+1, and X+2 (since
N=3).  when the repair is finished are nodes X, X+1, and X+2 all in sync
with respect to node X's data?  or does X have the latest data and X+1
and X+2 still in need of repair?  since merkle trees are calculated for
all replicas, seems like a good time to sync all of them.

i understand that X+1 and X+2 are replicas for nodes other than X and
may still need repairing.
