1600091 : Access to /data/dust/user/scheerth/¶

Created: 2026-05-11T13:21:41Z - current status: new¶

Anonymized Summary: A user ([REQUESTER]) is asking whether it is possible to grant another user ([TARGET_USER]) access to a specific folder (/data/dust/user/[REQUESTER_FOLDER]/) on the Maxwell cluster.

---

Solution/Next Steps: Access to /data/dust directories is managed by DESY IT. To grant permissions to another user, the following steps are recommended:

1. Check Current Permissions: Verify the current access rights of the folder using: bash ls -ld /data/dust/user/[REQUESTER_FOLDER]/ Ensure the folder is not restricted by default policies.

2. Modify Permissions (if applicable): If the folder is owned by [REQUESTER], they can grant read (r), write (w), or execute (x) permissions to [TARGET_USER] via: bash setfacl -m u:[TARGET_USER]:[permissions] /data/dust/user/[REQUESTER_FOLDER]/ Example: setfacl -m u:[TARGET_USER]:rwx /data/dust/user/[REQUESTER_FOLDER]/

3. Contact Support (if needed): If the folder is part of a managed namespace (e.g., group-owned or restricted), [REQUESTER] should contact maxwell.service@desy.de to request access for [TARGET_USER]. Include:

4. The full path of the folder (/data/dust/user/[REQUESTER_FOLDER]/).
5. The username of [TARGET_USER].
6. The required permissions (e.g., read-only, read-write).
