Rolling Restart in a Cluster
You can do a rolling restart of your cluster, where you keep your cluster up and running throughout the process via HA.
To shut down a node:
sdb-admin stop-node command will display this query:
Continue to stop the node(s) without taking a database snapshot?
Enter 'n' at the prompt.
To restart a node:
Restart the nodes in any order and combination, ensuring all the time, you have enough nodes up to keep the cluster running.
If you frequently need to stop all nodes on one host it is advisable to use the load-balanced mode of HA.
In case you do not plan to attach a leaf back again, then the REBALANCE PARTITIONS command should be used.
