Using Globus to access Lustre

Fermilab provides access to the Lattice QCD Lustre filesystem through Globus Online. To use this facility you will need to perform a one-time registration step as detailed in Step 1 below. After the registration step has been completed successfully follow steps detailed in Step 2 to access your files in Lustre using Globus Online.

Step 1 One time registration.

Step 1.1 Fermilab Kerberos account

If you are reading this document, you should already have a Fermilab Kerberos account and be authorized to use the Fermilab LQCD Lustre filesystem for read (and write). If you do not have a valid Fermilab Kerberos account please follow instructions listed on the New Users account page. If you need further assistance please email us at lqcd-admin@fnal.gov

Step 1.2 Register with Globus Online

If you have not registered with Globus Online already then registering with Globus Online for a new account is easy. Please go to www.globusonline.org and Sign Up for a new account. It takes a few minutes to setup a new account. Please watch over your emails for an email confirmation.

Step 1.3 Notify us of your CILogon Certificate Subject line

Go to cilogon.org, authenticate with your home institution (Identity Provider) and send email to hpc-admin@fnal.gov with the "Certificate Subject" line (red underline in the screenshot to the right).

The next section addresses the actual transfer procedures.

Step 2 Transferring files.

We have setup a dedicated Globus endpoint servers named lqcd#lq1 so users can access the Lattice QCD Lustre filesystem (lustre1) through Globus Online. If you have any questions or issues following the steps listed below please email us at lqcd-admin@fnal.gov. For Globus account related questions please contact the Globus support team.

Step 2.1 Login to your Globus Online Account using CILogon at https://www.globus.org/

Step 2.2 Make sure to use CILogon to authenticate yourself. Search your home institution and use that, the one shown in the screenshot (Fermi..) is an example. If Fermilab is your home institution then use that.

Step 2.3 Click on the Endpoints link to search or list the Fermilab LQCD Globus endpoint servers.

Step 2.4 Enter "lqcd fnal" (case sensitive) in the search bar to locate the endpoints. Click one of the listed endpoints to choose the one you wish to use. Recommended steps to follow are noted in the screenshot to the right.

Step 2.5 Click the Activate Now button to activate the endpoint.

Step 2.6 Click the Continue button to be redirected to the CILogon site for authentication.

Step 2.8 If all went well thus far, then you are ready to transfer files. You should be able to see the Lustre filesystem contents as shown in the screen shot to the left.
