Once you created the CSV file, you can start to configure the filesystem by using the
lustre_config script.

$ lustre_config
lustre_config: Missing csv file!

This script is used to format and set up multiple lustre servers
from a csv file.
Options:
-h help and examples
-a select all the nodes from the csv file to operate on
-w hostname,hostname,...
select the specified list of nodes (separated by commas) to
operate on rather than all the nodes in the csv file
-x hostname,hostname,... exclude the specified list of
nodes (separated by commas)
