The GPFS home storage system is currently offline. We are working to identify and resolve the underlying cause of the disruption, and will provide additional information as available.
Update 3:45 PM This outage started at about 1:55 PM. We've identified a set of nodes that may be causing this problem and are working to reset them.
Update 4 PM The system should be fully operational now. We've identified memory exhaustion on four compute nodes as the cause of the problem. Despite existing mechanisms to prevent the overutilization of memory, they were stuck in a state where there was not sufficient memory to respond to the storage cluster but still responsive enough to prevent an automatic recovery without them. We will continue to investigate the cause and work with the storage vendor to address this.
