Hi,
It is not enough to run the repair in one node, except if the node contain all the data (ex : 3 node cluster with RF=3).
In the general case, the best is to launch the repair in every node, with the "-rp" option (use -rp to repair only the first range returned by the partitioner)

Hi!
I apologize if for this naive question.
When I run nodetool repair, is it enough to run on one of the nodes, or do I need to run on each one of them?
Thanks
