Tape infrastructure

  • IBMLIB4 full?
  • No more JF tapes in supply makes it complicated to absorb peaks

Use cases

  • Features needed in production for 2026 run restart
  • Maintd monitoring tuning
    • Nothing to monitor cta-maintd once it is not running anymore as a forked process in cta-taped
    • Best practices to monitor running processes heartbeat style?
  • 2026-01-18 reporting issues during the WE
  • Reporting incident: Maintenance process was blocked on a single repack object and iterated only once on most routines at least reporting archived files
    • restarting cta-taped every hour on one DOwN tape drive allowed to report files every hour and ALICE could go through...
  • No more repack in production/cephUser
    • repack separation needs some improvements: what should be done on User side? Repack side?
