Couchbase kept failed in setting new key
I have a giant dataset in my couchbase,
As I was using some Virtual Machines that didn't met the basic requirement of production, I am trying to add the same number of nodes into the cluster, at the same time, removing the old ones.
However the rebalance seems to be stucked, and now they kept on failing to perform any "SET" operation.
Anything to be done?
