[Tetralith-users] Reboot of Tetralith login nodes Wednesday December 7th

[Mats Kronberg]

Dear Tetralith users,

On Wednesday this week (December 7th), we will update and reboot the
Tetralith login nodes.

We will keep downtime to a minimum, but the work may take anywhere from
30 minutes to 2 hours per login node.

Login node tetralith2 will be rebooted starting 08:00 CET.

Login node tetralith1 will be rebooted starting 11:00 CET.

Logged-in users will be logged out. Running and queued batch jobs will
not be affected.  Running interactive sessions will be terminated.

While one login node is rebooted, the other will be available, and new
SSH and ThinLinc sessions will be sent to the working login node.
