Who is affected:
All users of the CS Staff-managed public login systems, including the
cycles, courselab, and armlab systems.
What is happening:
CS Staff will upgrade the user-accessible servers in our infrastructure,
including cycles, courselab, and armlab.
The systems will be upgraded to the latest Springdale 9 distribution for
the x86_64 architecture and RockyLinux 9 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. Please keep in mind
that these servers are only reachable from inside the CS network.
cycles-test
courselab-test
armlab-test
SPECIAL NOTE: As we are reloading the Linux servers, all crontabs will be
deleted. If you have crontabs that you wish to persist, you will need to
back up your crontabs before the downtime and restore them after.
Why is it happening:
This is part of the routine maintenance of the publicly-accessible systems
and will bring newer versions of installed tools and software.
We will post updates to the status page: 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
