ITS staff has deemed that limitations to a server-side resource resulted in the service degradation. An upgrade has since been installed to prevent a similar occurrence happening in the future.
In addition to interruption previously described, eTD (Electronic Theses and Dissertations) and eHT (Electronic Honors Theses) will also be unavailable during this maintenance window (4/25, 5-7 a.m. EDT).
On Wednesday, 24 April, Applied Information Technology (AIT) will be running maintenance-related tasks for the distributed file backup service, Tivoli Storage Manager (TSM), backup.aset.psu.edu. Maintenance is scheduled to begin at 10:00 a.m. and conclude around 11:00 a.m. During this time, backup.aset.psu.edu will not be available for backing up or restoring files. The other TSM servers, saverestore.its.psu.edu and tsm.offsite.psu.edu, will not be affected during, or from these efforts.
One of the Kerberos servers had a hardware failure starting at 6:40 AM the Kerberos server scooby.aset.psu.edu (18.104.22.168) had a hardware failure. We manually restarted it at 8:15 AM and it was back in production as of 8:22 AM. We are looking into the details of the failure. It is currently operating normally now. During the outage, the other servers were functioning normally.
Listserv restarted at 11:35 PM on Friday, April 19. The cause of the restart was the adding a large number of new users to new lists. While it restarted and was doing work, it was not sending mail. We restarted it at 1:30 PM on April 20 and it was functioning again as of 1:45 PM. The large add was not normal and we are working on why this caused this outage.
