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 if you have any questions.
