[Snic-users] Planned stop Triolith, Kappa and Matter 2014-11-17 09:00

[Mats Kronberg]

Dear NSC users,

On November 17th, Triolith, Kappa and Matter will be unavailable from 09:00.

Start of downtime: 2014-11-17 09:00 CET
Estimated duration of downtime: 1-2 hours

During this stop we will change some settings in the new storage
system that cannot be changed while the system is running.

All login nodes (including ThinLinc) and compute nodes will be
unavailable during this time, and will be restarted during the stop.

Please note that this means that any running cp, mv, rsync, ...
processes you might be using to transfer data to /proj will also be
stopped, and you will have to restart them manually. We recommend
using rsync for file transfers.

Running and queued jobs will not be affected.

Queued jobs that have requested enough time that they cannot finish
before the downtime will not be started. E.g 7 day jobs cannot start
if there are less than 7 days remaining before the stop.

If you need to run jobs in the week before the downtime, you might
need to shorten your jobs.

Jobs that are in the queue before the downtime will remain in the
queue, and will be started normally after the downtime.

Hint to low-priority projects: short jobs will find it easier than
usual to run in the days immediately before downtime, as they don't
have to compete with longer jobs.

Vagn and other NSC systems are not affected.
