[Snic-users] Tetralith and Sigma unavailable February 13th-14th

[Mats Kronberg]

Dear Tetralith and Sigma users,

Tetralith and Sigma will be unavailable from 2024-02-13 at 07:00
CET. Duration: approximately two days.

This means that you will not be able to access Tetralith or Sigma at all
during this period. This include your data on the Centre Storage storage
system (/home and /proj).

Queued jobs that cannot be completed before 07:00 will not be
started. All logged-in users will be logged out at 07:00. Queued jobs
will remain in the queue and be started normally when the clusters are
back online.

During this maintenance window we will upgrade the system servers
(running job scheduler, etc.) to Rocky Linux 9 and reconfigure the
storage system (Centre Storage).
