An electrical power outage for maintenance purpose will be held Saturday 21th of October 2023 (12 hours long maintenance).

• All PSMN infrastructure will be powered off from friday 20th (starting 12h00) to tuesday 24th
  • login nodes, compute nodes & visualization nodes will be POWERED OFF at noon (12h00) friday
• /scratch/Cascade will be replaced with new hardware, hence
  • all data on scratch/Cascade will be ERASED upon migration
• you have three WEEK to retrieve remaining data from /scratch/Cascade

See our online documentation:

• https://www.ens-lyon.fr/PSMN/Documentation/

Summer break: PSMN will be on minimum staffing, and only respond to urgencies (power outage, cooling outage, fire, …) for the next coming weeks.

Important side note: /scratch/Cascade on Cascade cluster will be replaced (and thus data destroyed) by new hardware on the first weeks of September 2023.

Urgent security upgrades must be perfomed, with reboot. Impacted services: gateways (ssh.psmn, allo-psmn)

We have to make urgent hardware upgrades on a few fileservers. These need a reboot afterward, fileservers will be unavailable a few minutes, at most. Expect lags and delays during these upgrades.

impacted services: $HOME and /Xnfs shares (mostly everyone)

We are powering down half of each main cluster (E5, Lake, Cascade):

• Ease on cooling system on hot days,
• Energy saving (and cost)…

Powering up will occur “on-demand” (more than one day in PENDING state).
