Maintenance window -- COMPLETED

2018-01-10

Wednesday 2018-01-10

Monthly maintenance window begins at 0900 hours on the first Wednesday of the month. (That is  today.)

This time we will:

  • Upgrade Slurm, Linux kernel and other system software on Bianca, Dis, Fysast1, Irma, Milou, and Rackham.
  • Upgrade Linux kernel and other system software on Castor and Grus.

Bianca and Grus will be unavailable while we service them.

We will restart all login nodes of Fysast1, Irma, Milou and Rackham, probably only once.

Slurm queues on Fysast1, Irma, Milou and Rackham will be stopped, but access to Slurm commands will mostly work during the day.

Slurm queues on Bianca will be stopped and, most of the day, logins to Bianca will not be possible.

We plan to keep you informed about out progress with the maintenance with updates here.

UPDATE 2018-01-10, 16:00

Irma is up and running. Bianca, Milou, Rackham and Fysast1 are still down. We will continue security upgrades tomorrow (Thursday) morning.

UPDATE 2018-01-11, 15:15

Irma, Milou, Rackham and Fysast1 are up and running. Bianca is still being tested. Hopefully Bianca will be back today.

Bianca is now up, however, graphical login is not working right now. Text login works fine (http://www.uppmax.uu.se/support/user-guides/bianca-user-guide/).

We're still working on Dis and expect it to be up by tomorrow.
