[Nebula-users] Nebula unavailable 2020-08-11 9-11 UTC

[Kent Engström]

Hi,

we need to temporarily turn off the Stratus/Nebula storage system to
move the rack housing it to make place for a rack with 32 new additional
compute nodes. After talking to Ole we have scheduled this for Tuesday
11 August 9:00-11:00 UTC (11:00-13:00 CEST).

As we need to unmount the /home, /software and /nobackup/* filesystems,
we will need to stop/prevent jobs from running on the compute nodes and
logout users from the login node during the downtime.

There is a reservation in place to stop jobs from being submitted that
would extend into the downtime. As we get closer to next Tuesday, please
remember this and adjust your "-t" timelimit argument to
sbatch/interactive as needed if you want the jobs to start before the
downtime.

Best Regards,
