Hi Luzifer,

It looks like your Swap Space is not configured correctly for optimal Vertica performance. We recommend at least 2GB and your system only has 0.96GB. If you increase the size of your Swap Space on your OS to 2GB you should be able to install Vertica successfully.

You could suppress this warning by using the --failure-threshold option during installation. Please keep in mind that using that option could result in an unstable instance of Vertica. It also might hinder your database's performance, and most importantly, it is not supported in a production environment.

The following links have more details to help you:

• https://my.vertica.com/docs/8.0.x/HTML/index.htm#Authoring/InstallationGuide/InstallingVertica/RunTheInstallScript.htm

Let me know if this answers your question.

On host's where you get the error
you need to add below below lines on the file /etc/rc.local
/sbin/blockdev --setra 2048 /dev/sda1
Note: add for all the volumes
