Advanced Research Computing : Flux DataDen

Flux user logins are only created to allow users to access DataDen volumes via the umich#flux Globus endpoint. 

1) Run this command:

  • sudo /usr/arcts/systems/scripts/user-meld.pl -u <uniqname> -f <faculty uniqname> -g <group> -s <school/dept> -c <college>
    • -g = group

      • You can find valid groups by running: cat /etc/group | grep "<group>"

        • For example, if someone's Department is Chemistry, I would cat /etc/group and grep for "chem". In this case, this is the group I would use in the script: chem:x:141803:markmont,cja,mrchampe.

        • When dealing with a complicated Department name, being as broad as you can be when greping for a group is better. The naming schemes aren't the best.

    • -s = department

    • -c = college 

2) Run Ansible: sudo /usr/arcts/systems/scripts/ansibleSync.sh

3) Add user to MCommunity Flux group (hpc-users-Flux):

  • Go to MCommunity.umich.edu.

  • Log into the site with your uniqname and password.

  • Click on the 'Members' tab.

  • Click the 'Add Members' tab.

  • In the 'Add Members' box enter the new user's uniqname and click the 'Save Changes' button on the bottom of the page.

  • You should see a status message indicating that the user is now a member of the group. To double check, search for their uniqname in the list of members. The user should now receive any notifications about Flux.

4) You may need to ask the systems team to check if the user's home directory was created on the Flux-Xfer nodes. Sometimes it happens and sometimes it does not. if the user does not have a home directory on one of the Flux Xfer nodes it may prevent them from being able to access a storage volume on Flux. 

Deactivating a Flux User Account (Take me off mailing lists)

If a user is requesting to be removed from our "mailing lists", and this happens quite often when maintenance updates are sent through Footprints, they only get removed from the mailing list if we also remove their account.

This is because, it is required that each user is on these mailing lists so we can facilitate maintenance updates, and other news. So if they want to be taken off the mailing lists, then they can't have a User Account.

If the user does not have a valid standing with the University, we will just go ahead and remove their account without their consent

Reactivating a user on Flux

To reactive at a user, you would create the user as if they were brand new.  All of the needed components for creation are needed for reactivation.
