We have been informed that the DC ENSL cooling system is back online.

Partitions Lake and Lake-premium are back at full capacity. Frequencies resume following the usual pattern (minimum frequency by day, maximum frequency at night).

• Cooling system is still under heavy load (and awaits repairs)
  • Lake partitions are reduced, and frequencies set at minimum
  • Cascade partitons have frequencies set at minimum

• Scratch Cascade is almost full
  • please cleanup, before I do…

  • find /scratch/Cascade/$USER/ --dry-run -type f -iname '*' -ctime +180 -exec rm -f {} \;

  • find /scratch/Cascade/$USER/ --dry-run -empty -type d -delete

remove –dry-run for thrilling action.

“Depuis 11h, un problème de groupe froid (1/4 en rade) affecte le Data Center (salle SING).

Nous devons impérativement limiter la chauffe de nos installations en les arrêtant ou en limitant leur fréquence.”

There's a problem with datacenter cooling system. Frequencies will be reduced and unused nodes will be powered off during all week-end.

edit: Lake & Lake-premium are in drained mode for the WE: running jobs will finish, queued jobs will stay queued.

If it is not enough, Cascade & Cascade-premium will endure the same fate, or worst (poweroff…).

Probably because a high energy particule went by, scratch/Cral went awol around 11:00.

(for real, reason unknown, but 2 servers of the pack suddendly decided that “no.”)

Plan B applied, with conviction, things should be back to normal.
