Verifying the Nodes

You can use the check command to verify that the nodes specified in the Stanza file are ready to be installed. The check command does not check the Stanza file and does not do any provisioning or installation. The check command runs the same checks that the Installer runs during its Verification phase. For example, it checks that the nodes have the right OS version, that they have enough disk space, and that they have enough memory to support installation or other Installer operations.

This example verifies the nodes specified in the sample_advanced_demo.yaml file. The -nv option specifies that certificates will not be checked and the output mode is verbose. The -t option, which is required, specifies the use of a template file:

./bin/mapr-installer-cli check -nv -t sample_advanced_demo.yaml
