Cluster Maintenance - Hansen/Peregrine1

September 22, 2015  8:00am – 10:00am
Hansen, Peregrine1

Update: September 22, 2015 1pm

The work affecting Hansen and Peregrine1 scratch filesystems has been completed and the clusters are back in full production.

Original

The Hansen and Peregrine1 cluster will be unavailable beginning at Tuesday, September 22, 2015 from 8:00am – 10:00am, for scheduled maintenance. The cluster will return to full production by Tuesday, September 22nd, 2015 at 10:00am.

During this time, Carter's scratch will be de-coupled from Hansen/Peregrine1. To ensure Hansen and Peregrine1 are not impacted by the separation, scheduling will be paused and access to scratch files will be unavailable.

The Hansen and Peregrine1 scratch filesystem will be unavailable for 1-2 hours. Any running job using scratch will block on I/O and appear to hang. Jobs will resume normally once access is restored.

Any PBS jobs which request a walltime which would take them past Tuesday, September 22, 2015 from 8:00am – 10:00am will not start and will remain in the queue until after the maintenance is completed.
