Comment 1 for bug 1401266

Can you confirm that the instances you configured had storage allocated beyond the boot disk ? There should be at least one UNMOUNTED and UNFORMATED storage spindle on each instance that will support the mapr-fileserver service (which for this simple charm is all nodes).

If there is a way to enforce this in the manner that cpu_cores or memory is enforced, I"m happy to add those details to the documentation.
