Vertica copy cluster ports

Issue/Introduction

What ports need to open and in what direction for copy cluster to work. 

Trying to find clarification on this.

We want to use copy cluster from our production instance to our stage instance.

This raises red flags as cross instance communication is frowned upon greatly.

I have 50000 and 5433 FROM prod TO Stage opened and didn't cause an issue due to it not being bi directional.

Then I discovered that 22(ssh) would need to be opened between all primary and backup nodes bi-directionally. 

 

 

Environment

Release : All Supported Releases

Component : Vertica - copycluster

Cause

copycluster is a vertica utility that uses rsync and ssh to move data between vertica nodes

Resolution

Ports 50000 and 22 are the only ports that need to be open on destination cluster for copycluster.

The source nodes rsync to port 50000 on destination cluster.

It uses 22 to ssh into the destination nodes.

both ports should be bi-directional.
