Lustre issue on G100

Dear Users, 
this is to inform you that yesterday in the late afternoon, one of the G100 Lustre servers suddenly rebooted. This caused filesystem issues on compute nodes that may have caused the crash of running jobs. Currently, the problem is solved except for the affected compute nodes that have been drained from production to be fixed. We are investigating the cause of the reboot to prevent future events.
We apologise for the inconvenience.
 
Best regards,
