PACE A Partnership for an Advanced Computing Environment

Short duration of unavailability (Feb 3, 2015)

Filed under: tech support — Semir Sarajlic @ 9:56 pm

On Feburary 3, at 7:00am, in coordination with our Network Team:

– Network team will have one of the main PACE firewall appliances rebooted in order to fix some isses we have been having with these appliances. This may cause a disruption in networking from outside of PACE in to the head nodes of all PACE clusters.

– PACE will also reboot all of the head nodes for PACE clusters to enact patches to fix the GHOST vulnerability.

These disruptions will result in a 15 minutes period of unavailability for the head nodes. Any login sessions and data transfers into PACE established prior to that time will be terminated, and any processes running on the head nodes themselves will also be terminated. Submitted and running user jobs, however, will remain unaffected, as this will only affect the connections from outside of PACE to inside — all internal operations will function as normal.
