Topics for this week

  • Space status - Armen
    • Reprocessing starts tomorrow, 1.5-2B events (50-50 DATA-MC)
    • Did cleaning at AGLT2, MWT2, SWT2: sites have ~30% free space now
    • SLACT2, NET2: lost of new free storage
    • BNL deletion backlog gone - free space looks ok. Deletion rate is now 10 Hz (compared to 2 Hz before). No problems at this rate.
  • Deletions status - Hiro, Wensheng, Armen
    • Armen - many legacy old (non space token) sites cleaned up and removed, will need to keep BNLPANDA (still not decided about BNLDISK, BNLTAPE)
    • Hiro - request was sent to deletion service yesterday, gone from DQ2, but not SRM yet
    • Wensheng - going ok so far
  • local cleanup or PRODDISK? Dark data cleanup? - Charles
    • Stopped cleanse at MWT2, so dark data is building up from pandamover
    • ccc is run every day at MWT2, it sees discrepancies periodically from central cleanup
    • Pandamover should register _dis datasets again - KD will follow up
    • All sites - run ccc with long cutoff (one week or older)
  • Hot issues
    • Flat file for space reporting for Bestman sites - Patrick, Wei will follow up
  • AOB
