How do I remove a node from a cluster without losing data?


#1

Hi,

I have a cluster of 4 nodes with multicast heartbeat, without any replication. How I can remove node from the cluster without loss of data?

With replication of 1 (meaning no replication), the only method to remove a node from cluster without loss of data would be to do a backup of that node before removing it.
