Preparing qglobus12

Preparing qglobus12#

The qgloubs12 data transfer node performs data transfers involving the Northwestern Quest RDSS collection. This node is part of the Quest HPC infrastructure and does not have RDSS mounted by default.

Complete the following steps to connect your NetID to the file paths you use on RDSS/FSMResFiles and use your NetID to mount these paths to qglobus12.

  1. Find the full path to your share: Repeat for each unique path you access on RDSS/FSMResFiles. This information is required for Step 2.

  2. Submit a configuration request by filling out the Request access to RDSS via Globus form . This step is performed once per path from step 1.

  3. Give the qgloubs12 data transfer node access by mounting your share to the data transfer node using your NetID credentials. This step must be completed periodically due to system maintenance.

See below for detailed instructions on finding your path and mounting your share to the data transfer node.

Find Your Share Path#

To find the full path to your RDSS/FSMResFiles share, use the following operating system specific instructions.

To find your path on a Windows Computer:

  1. Connect to your RDSS share

  2. Open Windows Command prompt by clicking the Windows search bar and typing cmd

  3. Type the following command: net use

  4. The output will look like the screen shot below

RDSS request consent screen

Examples:

  • \\resfiles.northwestern.edu\share-name\

  • \\fsmresfiles.fsm.northwestern.edu\fsmresfiles\DEPARTMENT\RESEARCH_GROUP\

To find your share path on a Mac:

  1. Connect to your RDSS share.

  2. Navigate to the location of your share in Finder.

  3. With that folder open in Finder, type Command-I (the Command ⌘ key and the letter I key) to open the “Info” window about this folder, or right-click on the folder icon and choose “Get Info” from the menu.

  4. In the window that pops up, under the “General” section, copy the path in the Server field. It will start with smb:// followed by your access zone, then a path to the share separated by slashes. See screen shot below.

Examples of share paths:

  • smb://resfiles.northwestern.edu/share-name/

  • smb://fsmresfiles.fsm.northwestern.edu/fsmresfiles/DEPARTMENT/RESEARCH_GROUP/

To find your path on a computer running Linux:

  1. Run the mount command in the shell. The output will include all volumes mounted to your machine. The output for your smb mount will look like one of the following:

netid@resfiles.northwestern.edu/share-name on /mnt/share-name
netid@fsmresfiles.fsm.northwestern.edu/DEPARTMENT/RESEARCH_GROUP on /mnt/path

  1. Replace netid@ with // and remove on /mnt/... from the line of output with your share name.

Examples of share paths:

  • //resfiles.northwestern.edu/share-name/

  • //fsmresfiles.fsm.northwestern.edu/fsmresfiles/DEPARTMENT/RESEARCH_GROUP/

Request access to the data transfer node#

Use this information to submit a configuration request . You will receive an email when the process is complete. Repeat the process for other paths you need access to through Globus.

Mount your share to the data transfer node#

After your share is configured on the data transfer node, follow these steps to mount your share/folder to the data transfer node.

  1. Make sure you are either on campus, or are connected to GlobalProtect VPN . The qglobus12 node only accepts connections from certain IP addresses and your connection will fail if you are not associated with a Northwestern IP address.

  2. Open your terminal program of choice and connect to qglobus12 using the following command replacing netid with your Northwestern NetID. Enter your NetID password when prompted.

$ ssh netid@qglobus12.quest.northwestern.edu

  1. This operation will automatically mount your RDSS/FSMResFiles share and log you out of the server after 5 seconds. The share will remain mounted after you end your terminal session.

Note

Your share/folder will unmount if qglobus12 is restarted as a part of Quest operations. If you ever get a “permission denied” error when accessing your files, follow these steps again to remount your share. If the error persists, email globus-help@northwestern.edu .
