1594771 : NAF account problem. Cannot access home directory

Summary of the Issue

A user reports that upon logging into the naf-cms server, their AFS home directory (/afs/desy.de/user/a/[USERNAME]) appears to be missing or inaccessible. The system attempts to create the directory but fails with "Read-only file system" errors, suggesting either: - The AFS volume is corrupted or offline. - The user lacks sufficient permissions to create/modify the directory. - The AFS cell (desy.de) is experiencing technical issues.

Possible Solutions

  1. Check AFS Status
  2. Verify if the AFS service is operational (e.g., fs checkservers).

  3. Confirm if other users are experiencing similar issues.

  4. Restore Home Directory

  5. If the directory was accidentally deleted, DESY admins may need to restore it from backups (AFS is backed up).

  6. Alternatively, the user’s AFS volume might need to be re-created.

  7. Permissions Issue

  8. Ensure the user has the correct AFS permissions (fs listacl /afs/desy.de/user/a/[USERNAME]).

  9. If the directory exists but is read-only, admins may need to adjust ACLs.

  10. Temporary Workaround

  11. If the issue is temporary, the user could work in /tmp or another writable location until resolved.

Next Steps

  • The user should contact DESY/NAF support (e.g., via ticket or email) to investigate the AFS volume and restore access.
  • If the problem persists, admins may need to check the AFS server logs for errors.
