[Halld-offline] reminder: IT Division Maintenance Period Set for Tuesday, Dec. 19

The IT Division is planning a maintenance period for 5-10 p.m. on 
Tuesday, Dec. 19. During this time, all MIS applications will be down 
while patches are applied to the backend databases; plan your work 
accordingly. There will be a few short network outages while systems are 
updated and rebooted. Also, Windows and Linux patches will be released 
to all Jefferson Lab-managed desktops and server systems. Overnight, 
some services may have a short outage while the underlying server is 
rebooted to finalize patch installation. Additionally, the www.jlab.org

any questions or concerns about this maintenance period, contact the IT

Dear JLab Scientific Computing and HPC Users,

There will be a brief interruption to the new /work fileservers (and HPC 
/home, /dist) at 9am on Tuesday, Dec 19, to add a new JBOD disk shelf 
for additional storage space. During this time, file access from 
scifs17enp and scifs17hpc will stall until service is restored.

Also, SIngularity 2.4.2 will become available, via the module command.

Regards,
Sandy
