Requin is back in service: nodes are expected to behave as before, but /scratch will be decommissioned.

Requin’s local storage (ie, not home directories or global work) has not been recommended for some time now, and is no longer usable after the recent power outage killed 4 disks at once in a single array.

Campus facilities has tentatively required a brief outage of our chillers, which will require shutting down all systems located in the McMaster datacenter: Wobbie, Requin, and Iqaluk.

If finalized, this outage will take place Friday, February 26, between 7:30-8:30am. Systems will avoid starting jobs leading up to that time, and will be shutdown shortly before the outage. Systems should return to normal service before noon.
