Environment

DX NetOps Performance Management releases r21.2.3 or newer that include the Vertica 10.x release update

Cause

The root user has an alias set up for the df command.

Resolution

When the Vertica installation runs the root user is utilized to run the following command on the cluster nodes.

df --portability /tmp | tail -1 | awk '{print $4}'

If that command returns a non-numeric value it will trigger an install failure. For example if the following is run we see the non-numeric value returned.

[[email protected]<NodeName> ~]# df --portability /tmp | tail -1 | awk '{print $4}'
2.0G

As the root user running the following to check for configured aliases does return one for the df command.

#alias |grep df
Alias df='df -h'

To resolve the issue disable the alias for df command for the root user.

After the install is run to completion, the alias can be reconfigured.
