Date: Tuesday, January 29, 2019 (07:00-15:00)

Who is affected:
All users of the CS department computing.

cycle servers, ionic cluster, web content, home directories, CIFS, etc.

Why is it happening:
This is necessary in order to fix numerous bugs on our file system. In
addition, it will get our storage aligned with the latest operating system, which is crucial for any of the future storage hardware upgrades.

Please keep in mind that all of the above services will not be unavailable for the whole duration of the downtime. We do not expect an outage to last more than an hour, but cannot give an exact time of the reboot.

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.
