Subject Re: nodetool repair
Date Wed, 22 Sep 2010 10:27:26 GMT
Hi all,
just wanted to make sure that I get this right:
What this means is that I have to schedule repairs only on every RFs node?
So with 4 nodes and RF=2 I would repair nodes 1 and 3
and with 6 nodes and RF=3 I would repair nodes 1 and 4
and that would lead to a synched cluster?
