http://alerts.its.psu.edu/service-l The Information Technology Services (ITS) Alerts System is a rapid-delivery method used to distribute timely information on major ITS services, unexpected outages, and maintenance schedules to the Penn State community. en-us Copyright 2009 The Pennsylvania State UniversityTue, 24 Nov 2009 17:34:40 -0500 http://alerts.its.psu.edu/alert-1213
ITS will continue to monitor and tune the service as needed however it is expected that the new Directory Servers will greatly out perform the old version. The new version uses a much more robust, multithreaded replication model and tests have shown the new servers performed orders of magnitude better with proper tuning. This is expected to resolve the user and group account information lookup problem with the CIFS service.]]> Tue, 24 Nov 2009 17:34:39 EST http://alerts.its.psu.edu/alert-1304
Note that some services related to the LDAP upgrade may still be unavailable. See for progress.

ITS will report on the root cause when it has been confirmed.]]> Sun, 15 Nov 2009 17:50:04 EST http://alerts.its.psu.edu/alert-1292 Complications during a planned hardware upgrade of a CIFS Gateway led
to an outage outside the established maintenance windows, and degraded
some web services.

Details:
At 7:00AM, Wednesday November 04, one of the six CIFS gateway servers
became stuck in a bad state while attempting a graceful shutdown.
Said state caused a steady increase in load on those PASS nodes
attempting to access the filesystems being touched by the bad CIFS
gateway. As a result, each of the CIFS gateways gracefully removed
themselves from the loadbalancer after crossing the maximum load
threshold, resulting in the overall service outage.

In addition, www.personal.psu.edu and php.scripts.psu.edu are known
to have been impacted, experiencing service degradation due to the
state of those filesystems being touched by the PASS node in a bad state.

All services were restored to full functionality at approximately
7:50AM. Debug data has been gathered and we are working with the vendor
to permanently resolve the root cause of this issue.]]> Wed, 04 Nov 2009 09:11:49 EST http://alerts.its.psu.edu/alert-1283
ITS staff have taken diagnostic information from the failing servers and relayed it to the vendor for analysis.]]> Thu, 29 Oct 2009 21:48:15 EST http://alerts.its.psu.edu/alert-1277 Tue, 27 Oct 2009 11:51:01 EST http://alerts.its.psu.edu/alert-1242 Thu, 24 Sep 2009 15:12:44 EST http://alerts.its.psu.edu/alert-1236 Mon, 21 Sep 2009 11:02:07 EST http://alerts.its.psu.edu/alert-1200
