Who is affected:
All users of the CS Department âpublicdbâ database server, including
any dependent web properties and all CS Department Beowulf high-performance
computing cluster users, known as ionic.
All users of CS Department administrative web properties (Dropbox, CS
Guide, the Main website, etc.)
What is happening:
During this window, the âpublicdbâ database server will be replaced
with a newer server. All existing MariaDB databases will be migrated to the
new server, so no data loss is anticipated. However, while Slurm jobs will
continue, new jobs cannot start during the migration.
In addition, the database server underlying the administrative systems
will be upgraded and replaced. During the upgrade, all database-dependent
administrative systems will be unavailable. This includes the CS Dropbox
service, the main website, the CS Guide, ADM, and any content feeds
provided by CS Staff.
Why is it happening:
The old servers running MariaDB 10.1.24 will be upgraded to newer ones
running MariaDB 10.5.22.
phpMyadmin web interface will be upgraded from version 4.4.14 to 5.2.1.
This is part of regular maintenance to enhance system performance and
security.
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
