If you purchased additional storage, you should see a subscription to Project Storage in your project overview.  Currently the usage shows 0, although this is not an accurate depiction of your actual usage.  Eventually, you will be able to see an up-to-the minute view of your storage usage, however for now you must take an extra step to find out your current project storage usage.  You can do this in one of two ways:


1.  Return to the Coldfront homepage and click the link 'Get Isilon Storage Quota' under the middle column labeled Isilon Storage Quotas.


2.  Login to the cluster and run the iquota command.  Instructions can be found here


The base storage that all PIs receive for free does not show up as a separate subscription.  Please use the link above for instructions on how to check your quota from the command line.


Information on how to find out your budget storage usage and quota can be found here
