[Krypton-users] Krypton login node downtime tomorrow for OS update

[Kent Engström]

Dear Krypton Users,

we need to install a recent (received today) kernel security patch
on Krypton before the Christmas holidays.

Together with the user representatives, we have scheduled this for
tomorrow Thursday 18th, 15:00-17:00 CET.

The login node (and the system server) will be rebooted. We will also
start a rolling update of the nodes as they become idle (should not
affect running jobs).


PS! The Nehalem nodes n[301-428] are scheduled to be turned off at the
end of the year.

Best Regards,
