1609487 : Please Cleanup your AFS Directory !¶

Created: 2026-06-16T11:27:52Z - current status: new¶

Anonymized Summary¶

Issue: A Condor scheduler (bird-htc-sched22.desy.de) appears to have crashed, affecting most users except ATLAS and CMS. Errors include: - A security negotiation failure when fetching ads from the scheduler. - A worker node failing to write logs due to a directory containing too many files (errno 27: File too large). - Excessive log files accumulating in /afs/desy.de/user/[REDACTED]/.../logs/.

The reporter suggests cleaning up the directory and moving log files to DUST storage per DESY’s guidelines (Confluence link).

Suggested Solution¶

1. Cleanup Log Directory:
2. Delete old/unnecessary log files in /afs/desy.de/user/[REDACTED]/B_to_K_nu_nu/lorenz_branch/B_to_K_nu_nu/logs/ to resolve the "too many files" error.

3. Follow DESY’s storage policies to avoid future quotas.

4. Redirect Logs to DUST Storage:

5. Configure Condor jobs to write logs to /dust/ instead of /afs/ if long-term retention is needed.

6. Scheduler Investigation:

7. Check the status of bird-htc-sched22.desy.de (security negotiation errors may indicate service issues).
