Date: Tuesday, July 12, 2022
Who is affected:
All users of the CS department computing and network infrastructure.
What is happening:
Hello, everyone.
In the next 3-4 weeks (exact date TBD), CS Staff will upgrade the
user-accessible servers in our infrastructure including cycles, ionic,
courselab, armlab, and the web servers. These systems will be upgraded to
the latest Springdale 8 distribution for the x86_64 architecture and
RockyLinux 8 distribution for the aarch64 architecture (i.e., armlab).
To help ensure a smooth transition, we currently have the new distribution
installed on the following servers for your testing:
cycles-test
courselab-test
armlab-test
As appropriate, please try out your scripts, assignments, etc. on these
servers and report any issues to us ASAP. With the new distribution comes
updated software versions and, in some cases, removed packages.
As we continue our own testing and incorporate feedback from you, we will
follow up with additional information including the specific cut-over date.
Why is it happening:
This is part of normal maintenance of the publicly-accessible systems and
will bring newer versions of installed tools and software.
We will post updates to the status page: http://www.csstaff.org
as necessary.
If this downtime will cause you undue hardship, please contact
csstaff@cs.princeton.edu immediately, so we can discuss options to reduce
any negative impact. Your patience is appreciated.
Sincerely,
CS Staff
