Vertica 6.1 - Single node to cluster
I've inhereted a single node Vertica 6.1 instance and now have a requirement to make it a cluster (also 6.1). I have performed copy cluster in the past between 3 node clusters although this is a bit different since the source Vertica instance in this case was installed as a single node (So they tell me).
My first question is how do I validate that it is indeed a single node install? When I go into adminTools, the option to add a node to the cluster is there so if I'm lucky I may just be able to add nodes to it.
Next question, if it is in fact single node and cannot be expanded, How do I magrate the data from the single node into the cluster? I was thinking of installing the new 3 node cluster, removing two of the nodes, doing a copy cluster to the single node that is still in the new cluster and then adding the two nodes back in. Will the copy cluster from the non-clustered source infact make the destination non-clusterable?
Being that we dont want to loose the data in the existing vertica server, how do I go about migrating to a cluster?
