[downtime] CS Ionic Cluster Downtime, Tuesday, July 11, 2017,

Tue, 06/27/2017 - 9:11am

Date: Tuesday, July 11, 2017 (09:00-12:00)

Who is affected:
All users of the CS Department Beowulf high performance computing cluster,
known as ionic.

What is happening:
During this window, cluster management and job scheduling system slurm and
its database will be upgraded. No data loss is anticipated.

Why is it happening:
As part of the routine maintenance of our systems, the old slurm package
(running 15.08.8) will be replaced with a newest version – 17.02.4. This
is part of regular maintenance to keep systems up-to-date.

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

[downtime] CS User Database Server Downtime, Tuesday, July 11, 2017,

Tue, 06/27/2017 - 9:06am

Date: Tuesday, July 11, 2017 (09:00-10:00)

Who is affected:
All users of the CS Department “publicdb” database server, including any
dependent web properties.

What is happening:
During this window, the “publicdb” database server will be replaced with a
newer server. All existing MySQL databases will be migrated to the new
server, so no data loss is anticipated.

Why is it happening:
As part of the routine maintenance of our systems, the old MySQL server
(running MySQL 5.1.73) will be replaced with a newer server running MariaDB
10.1.23. MariaDB is an open-source enhanced, drop-in replacement for MySQL.

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
