NFS DCC Access Tutorial
Overview
This NFS DCC tutorial guides you through:
Before you start
NFS DCC Volumes can only be created in Research Groups Projects in Research Toolkits. This tutorial assumes you already have a Research Group project and an NFS DCC Volume within that project. If you do not know how to do this, just follow our Quickstart tutorial for creating a project, and Storage Creation and then come back here!
Part 1: Access Your Storage in Globus
Step 1: Get NFS DCC Name
Go to your project where you created the NFS DCC volume. Here, you should see the name of your NFS volume. The mount location for your NFS DCC volume will be /nfs/volumeName, replacing volumeName with what you see in your Research Toolkits project. In the below image, the name of the NFS DCC volume is 236-rm145DCC01. You should have also received an email when your NFS DCC volume was completed with the mount location.
Step 2: Access NFS DCC Volume
There are multiple ways to access your NFS DCC volume: Globus, SSH, and Open OnDemand.
For Globus, make sure that you've signed into your Globus account first. You can follow these instructions for accessing and using Globus. Once created, you can login to Globus and search for the "Duke Compute Cluster (DCC) Data Transfer Node" collection. Once found, for the path, enter /nfs/volumeName, replacing volumeName with your NFS DCC volume's name.
For SSH access, follow these login instructions. Once completed, you can then use the command cd /hpc/group/volumeName, replacing volumeName with your NFS DCC volume's name. For example, using the example above, you would enter:
cd /hpc/group/26-rm145DCC01
For Open OnDemand, sign in with your netID and password, and then click on Files > Home Directory. From here, click on "Change directory" and then enter the path to your NFS DCC volume.
Part 2: Move Files to your NFS DCC Volume
To transfer files into your NFS DCC volume, you can use Globus, SSH, or Open OnDemand.
For Globus, you have the option of using the Globus UI or the Globus CLI.
If you want to use a command line interface like terminal with SSH, you can use SCP for individual file transfer or rsync for larger numbers of files.
If you prefer the Open OnDemand environment, you can upload or download smaller numbers of files by selecting Files > Home Directory, changing the path to /nfs/volumeName, and then selecting the Upload or Download option. Note, there is also a Globus link here that will take you to the Globus page for file transfers.
Overall, we recommend Globus for copying or transferring data. It's a reliable service that's fast and can handle the data transfer in the background, freeing you up for other tasks.
