[Bi-users] Bi login node reboots on June 21

[Kent Engström]

Dear Bi Users,

we need to reboot the login nodes (and the system server) to complete
the upgrade to CentOS 6.8.

As some filesystems will be down on June 21 from 13 to 19 CEST (see
below), we decided to plan the reboot period for 17-19 CEST the same
day.

As usual, login node processes and interactive jobs will be killed,
while batch jobs should survive, as we will update compute nodes between
jobs.
