OnDemand Version Update

On Wednesday, December 11 from 9am-915am there will be a short interruption of service for OnDemand to deploy a new version of the portal. It will deploy some updates to the web apps and infrastructure. **During this interruption any active shell connections, noVNC connections, and file transfers will be terminated. Afterwards one should be able to reconnect to running VDI and iHPC sessions.** Contact oschelp@osc.edu if there are any questions.

Availability and Restrictions

Versions

The following versions of ls-prepost are available on OSC clusters:

GPFS filesystem Problem

We are having issues with GPFS filesystem (both project and scratch) on all clusters. It started around 3:08 PM, Oct 24, 2019. This also causes the inaccessibility of OSC OnDemand. We are not clear whether there are any job failures due to this problem. We are working to resolve the issue now. We will keep you posted and apologize for any inconvenience. Please contact oschelp@osc.edu if you have any questions.

Ls-dyna license outage

The ls-dyna license server that OSC is hosting has not been available since Oct 15, 2019. This outage is due to hardware failure on the server. We apologize for any inconvenience this may cause you. Please contact oschelp@osc.edu if you have any questions.

Rolling reboot of Owens starting from Oct 10, 2019

We are having rolling reboots of Owens cluster including login and compute nodes, starting from October 10, 2019, to update Kernel and root filesystem. The rolling reboots won't affect any running batch jobs, but users may experience longer queue wait time than usual on Owens. A reboot of the Owens login nodes is scheduled at 8AM on Friday, October 11, 2019. The outage is expected to last 5-10 minutes and SSH sessions on Owens will be disconnected during the outage. We apologize for any inconvenience this may cause you. Please contact oschelp@osc.edu if you have any questions.
