Bypassing Vertica Installation Warnings for NetOps Data Repository

Products

• CA Performance Management
• Network Observability

Issue/Introduction

This procedure addresses installation failures where the dr_install.sh script exits due to Vertica prerequisite warnings (such as LVM detection or block size mismatches), even when the dr_validate.sh script passes.

Issue/Introduction

The dr_install.sh script may fail and exit after logging warnings, such as:

• WARN (S0170): lvscan (LVM utility) indicates some active volumes
• WARN (S0165): Vertica prefers a filesystem block size of 4096 '/dev/sdb1' = 512.

Environment

• DX NetOps Performance Management: All Supported Versions

Cause

By default, the Vertica installer is configured to treat both WARN and FAIL conditions as fatal errors.

Common triggers include the detection of Logical Volumes (LVM) anywhere on the system—even if not used for /data or /catalog

or hardware reporting 512-byte block sizes that the installer flags despite OS-level compatibility.

Resolution

To allow the installation to proceed past these non-critical warnings, you must modify the installer configuration to lower the failure threshold.

1. Navigate to the Data Repository installation directory.
2. Open the drinstall.properties file in a text editor.
3. Add the following parameter to the file: AllowVerticaInstallWarnings=true
4. Save and close the file.
5. Rerun the installation script with the properties file: ./dr_install.sh -p drinstall.properties

Additional Information

The AllowVerticaInstallWarnings parameter for the CA Performance Management script essentially sets the Vertica failure-threshold to the desired level.
