Summary

Properly requesting Locker Large-File Storage.

The following document explains the proper procedure to request Locker Large-File Storage. For more information on the LSA Research Storage program itself, please refer to the "LSA Research Storage" article.

Environment

Directions

  1. If it does not already exist, create a new MCommunity group that controls the provisioning for the volume. The recommended format is arcts-uniqname-admins. Add lsats-rci-research-storage as a member and owner of the new group, add arcts-helpdesk as an owner only, and add as a member and owner the appropriate existing group for the supporting regional team.

    NOTE: Be sure to set the member list to be viewable by anyone.

    Existing regional team groups are as follows:
    lsats-rci-bsb-chem-storage
    lsats-rci-easthall-storage
    lsats-rci-randall-storage

  2. Get the GID for this new group. See "GID Help", below.

  3. Navigate to the request form.

  4. Select the Locker category on the left, and the Add Locker Storage NFS card on the right.

    The remaining items on this list refer to fields on the request form that appears.

  5. Numeric User ID: Typically this is the requester's UID. See the Additional Notes section of this document if you are unsure how to find a user’s UID. For additional details, you can click the “?” icon for help.

  6. Provide a MCommunity Group: Set the MCommunity Group Name to the MCommunity group that you created in Step 1.

  7. Group ID: Use the GID that you obtained in Step 2.

  8. Permitted Hosts: If forward and reverse records exist in DNS, use the fully qualified hostname. If the records do not exist in DNS, provide the IP address.

  9. Enter a Directory Name: Use the prefix "lsa-" and the faculty/researcher’s uniqname.

  10. Select an Option Type: Select Basic + Snapshots + Replication.

  11. Size: Specify a size in terabytes.

Notes

UID Help

If you are unsure the UID of your user, you can utilize the ITS login cluster service to find it out. You will need to ssh to login.itd.umich.edu and then run the following command where you replace uniqname with the user's uniqname:

ldapsearch -x -LLL -h ldap.umich.edu -b ou=People,dc=umich,dc=edu uid=uniqname | grep uidNumber

GID Help

To get the GID of the MCommunity group, run the following command, replacing groupname with the desired MCommunity group:

ldapsearch -x -LLL -h ldap.umich.edu -b ou=User\ Groups,ou=Groups,dc=umich,dc=edu cn=groupname | grep gidNumber
