Issue/Introduction

How can i replace a failed vertica node that is down and the OS will be reinstalled?

Environment

CAPM 3.x

Resolution

Refer to the following vertica documentation:

 

https://www.vertica.com/docs/9.2.x/HTML/Content/Authoring/InstallationGuide/InstallingVertica/RunTheInstallScript.htm


The steps should be the following:

Example:

1. Reinstall the OS on server 2
2. From node 1 (The UP node), you should run: /opt/CA/IMDataRepository_vertica9/dr_validate.sh -p drinstall.properties to optimize the system and re-setup root public key
3. Refer to the link above to install vertica:

So the command I believe should be:

/opt/vertica/sbin/install_vertica --hosts node0002 \
            --rpm /opt/CA/IMDataRepository_vertica9/resources/vertica-9.1.1-0.x86_64.RHEL6.rpm \
            --dba-user dradmin

Where node0002 is the name of node 2 on your environment
   
4. Use adminTools from an existing node to restart the new host

Additional Information

The above steps assume that vertica will be installed on the same system, where the host name and IP remain the same
