ISSUE:

Unable to successfully install the Data Repository system

ENVIRONMENT:

CAPM (CA Performance Management)

SYMPTOMS:

The dr_validate.sh script completes successfully but the dr_install.sh script fails and exists, logging the following:

WARN (S0170): https://my.vertica.com/docs/7.1.x/HTML/index.htm#cshid=S0170
lvscan (LVM utility) indicates some active volumes


CAUSE:

Logical Volumes (LVMs) were detected on the system.

Vertica does not support installing the /data and /catalog directories on Logical Volumes.

Even though /data and /catalog are not on Logical Volumes, because a Logical Volume was detected elsewhere on the system, a WARN was logged.

By default, the Vertica install is configured to fail and exit on a WARN as well as a FAIL condition.


RESOLUTION:

Add the following parameter to the drinstall.properties file:

AllowVerticaInstallWarnings=true

This will allow WARN conditions so that the install completes. The install will only fail and exit if any FAIL conditions are met.

The parameter can be set anywhere in the drinstall.properties file.

After setting this parameter, re-run the dr_install.sh script


ADDITIONAL INFORMATION:

The AllowVerticaInstallWarnings parameter for the CA Performance Management script essentially sets the Vertica failure-threshold to the desired level. Refer to the Vertica documentation for additional information:
