[Tetralith-users] Tetralith login nodes reboots Thursday and Friday next week

[Mats Kronberg]

Dear Tetralith Users,

on Thursday and Friday next week we will install security updates that
require a reboot of the Tetralith login nodes. We will try to keep
downtime to a minimum but it may take up to 1 hour 30 minutes each.

Login node tetralith2 will be rebooted Thursday April 22nd starting at
13:00 CEST.

Login node tetralith1 will be rebooted Friday April 23rd starting at
09:00 CEST.

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.
