[Triolith-users] Triolith: service stop next Wednesday (2014-09-17 09:00)

[Mats Kronberg]

Dear Triolith users,

On Wednesday, September 17th, Triolith will be unavailable.

Start of downtime: 2014-09-17 09:00 CEST
Estimated duration of downtime: 4-8 hours

During this stop we will connect the new Centre Storage system to
Triolith (for testing purposes only), and do some initial tuning and
large-scale testing. The reason for the full service stop is that some
configuration changes cannot be done unless all compute and login
nodes are stopped.

Both login nodes (including ThinLinc) and compute nodes will be affected.

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.

Kappa, Matter, Vagn and other NSC systems are not affected.
