1600044 : CSSB GPFS project data folders move

Created: 2026-05-11T12:18:56Z - current status: new

Here is the anonymized and summarized version of the request:

Summary of Request

A former user’s data on the CSSB GPFS filesystem needs to be relocated to a group directory. The following folders: - /gpfs/cssb/user/[FORMER_USER]/Processing_Tests/20200629_StalledLASVdimers - /gpfs/cssb/user/[FORMER_USER]/Processing/20210318_LASVC_C8b/ - /gpfs/cssb/user/[FORMER_USER]/Processing/20200825_LASVC_Dimers/ - /gpfs/cssb/user/[FORMER_USER]/Processing/20200717_StalledLASVC - /gpfs/cssb/user/[FORMER_USER]/Processing/20200617_StalledLASV

should be moved (not copied) to: /gpfs/cssb/group/[GROUP_NAME]

Requirements: 1. Change ownership of the moved data to [NEW_USER]. 2. Adjust quotas if necessary to ensure the target folder can accommodate the data. 3. Reduce the original folder’s quota by the transferred amount (or the requester will handle it afterward).

Approval: Group leaders are aware and have approved the request.

Suggested Solution/Next Steps

  1. Contact CSSB IT/DESY IT
  2. The CSSB GPFS filesystem is managed jointly by CSSB IT (it@cssb-hamburg.de) and DESY IT (maxwell.service@desy.de).
  3. Since this involves ownership changes, quota adjustments, and data movement, the request should be directed to the responsible admins.

  4. Provide them with:

    • The exact source/target paths.
    • The new owner ([NEW_USER]).
    • Confirmation of group leader approval.

  5. Alternative: Self-Service (If Permissions Allow)

  6. If the requester has admin rights over the group directory, they could:
    • Use rsync to copy the data (preserving permissions/ownership with -a flag).
    • Change ownership with chown -R [NEW_USER]:[GROUP] /gpfs/cssb/group/[GROUP_NAME]/[FOLDERS].
    • Delete the original data after verification.

  7. Warning: Quota adjustments still require admin intervention.

  8. Quota Management

  9. The requester can check current quotas with: bash mmlsquota -j [FILESYSTEM_NAME] [GROUP_NAME]
  10. If the target group lacks space, the admins must adjust the quota before the transfer.
