Products

Issue/Introduction

We are doing an upgrade as sudo user.

dr_validate.sh completed successfully on all nodes.

 

dr_install.sh fails with the following error:

..

>> Starting installation tasks.

>> Getting system information for cluster (this may take a while)...

 

Error: It looks like xx.xx.xx.222 and xx.xx.xx.223 are the same host.

Hint: Each cluster host must be a distinct machine.

Installation FAILED with errors.

 

Installation stopped before any changes were made.

install_vertica script failed with exit code 1..........................[FAIL]

Environment

DX NetOps :: All Supported Versions

Cause

The install script was unable to resolve the hosts.

This could be caused by name resolution problems or sudo permissions.

Also make sure the Data Repository administrator is a member of the verticadba group and has not been removed from this group.
This is normally the group associated with the vertica database. An ls -al of the data directory would confirm

Resolution

Make sure that the hosts file on each node has an entry for all nodes.

 

Make sure that the sudoers file has all the required entries from the docset:

Configure the Sudo User Account Privileges for Data Repository Installations and Upgrades
