I have a x8 node production SMS cluster running a pretty old version of Cassandra. One of the nodes was powered down for the weekend. This single node was unable to communicate with the entire ring so my question is now that I've got the VM back up, what do we need to do?
Should I perform a cleanup in a specific order on the ring and once that is done, go back around the ring and do a repair -pr? Appreciate any advice on how to proceed here.
