UNIX Permissions
If you are accessing your Turbo storage through NFS, your access to those files/directories will be based on their UNIX Permissions. The Permissions are assigned at the object level by the User and Group Permissions assigned to those files. By default, only the creator of a file, and the users in the group inherited from the parent directory will be able to access a file.
For more information on UNIX Permissions, feel free to check out this guide, or ask your Unit IT Staff for help!
Active Directory Permissions
If you are accessing your Turbo Storage through CIFS, your access to those files/folders will be based on their Active Directory (AD) Group Membership. AD Group membership is owned and managed by Unit IT Staff. If you need to change permissions or access to CIFS/SMB Volume, contact your unit IT team for assistance!
Unix Groups
In order to set appropriate permissions, and provide access for multiple users on our clusters, local Unix groups must be created by ARC to properly administer your NFS Turbo volume. Any user addition or deletions to Unix groups on any ARC service must be requested by contacting us at arcts-support@umich.edu.
AD Groups
In order to set appropriate permissions, and provide access for multiple users in CIFS volume, AD groups must be created by your local IT department to properly administer your CIFS volume.
Multi-protocol volumes require advanced synchronization between your Unix Groups and AD groups. Contact your unit IT staff to help build these synchronization, and we will work with them to set it up.
Any user change requests will need to be directed towards your local IT department.
