Issue/Introduction

We ran the ./dr_validate.sh -p drinstall.properties in our lab as a pre-work for the upcoming Performance Management upgrade.  We want to clarify if running this validate script created changes in the Data Repositories.  The reason we ask because the result gave us the following message.

This script made changes that require a reboot of the system before we can proceed with the Vertica installation.  Please run this script after the reboot to ensure all pre-requisites have been met.

Could not enforce prerequisite compliance.
Data Repository Prerequisite Compliance Status on host DR_Hostname_Here -- FAIL!

Environment

Release : 3.7

Component : IM Reporting / Admin / Configuration

Cause

Yes, changes to some of the configuration items were made but as noted, will not take effect until the environment is rebooted.  Some examples:

Detected incorrect readahead parameter for /dev/sdb .....................[WARN]
Set readahead parameter for /dev/sdb to 2048 ............................[ OK ]

or

Detected incorrect swappiness setting - should be set to 1 for Vertica 8.1+ [WARN]
Set runtime swappiness to 1 .............................................[ OK ]
Set persistent value of swappiness to 1 .................................[ OK ]

Resolution

Make sure the Data Repository hosts are rebooted prior to being upgraded to ensure compliance with the required items.
