[Tetralith-users] Terralith login nodes reboots today, tetralith1 14:30-15:30 CEST, tetralith2 15:30-16:30 CEST

[Fredrik Nyström]

Dear Tetralith Users,

sorry for the short notice, we need to install a security update on 
Tetralith login nodes. We will try to keep downtime to a minimum but it 
may take up to 1 hour.

The login node tetralith1 will be rebooted today starting at 14:30 CET.

The login node tetralith2 will be rebooted today starting at 15:30 CET.

There is a mitigation in place since Wednesday but that has a side 
effect of restricting stack size to 30M.

Compute nodes are running a rolling upgrade since Wednesday evening.

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. So
if you're logged out at the times given above, just login again and
keep working.


Kind Regards,
