Vertica cluster expansion

naresh_way2

Hi,
I installed vertica on single node without localhost(or 127.0.0.1) that means the ip whatever i had for my system with ip (xxx.xxx.x.1).And I also installed vertica on another server with ip (xxx.xxx.x.2). Now I want to add these two nodes. But when I performed that through management console via add host,it shows me all hosts are participating. How do I add those nodes.
Please, explain me how to add them to make cluster.
Thanks in advance.

Can you post the hosts that are listed in your clusters (single node #1) and (single node #2)?

You can use this Linux command:

grep hosts /opt/vertica/config/admintools.conf

Hi jim,
I found that mistake.Before adding another node to single node we use update_vertica script.To do this we need to do backup.For this I want to create vbr configuration file but every time it gives me file name error.
I followed like this and I got error.

Hi,

Where are you trying to create the fullback.ini file? Do you have the privilege to write to that directory?

Thanks!
