How many total RS in the cluster? You mean u can not do any operation on other regions in the live clusters? It should not happen.. Is it so happening that the client ops are targetted at the regions which were in the dead RS( and in transition now)? Can u have a closer look and see? If not pls check the RS threads were they are getting blocked.
