Cathy Hancock - Client Relations <hancock@uchicago.edu> NSIT Thu, 29 Oct 2009 16:40:37 CST http://hp-announce.uchicago.edu/fullArticle.php?areaStatusChangeID=796 http://hp-announce.uchicago.edu/fullArticle.php?areaStatusChangeID=795 On the afternoon of Tuesday, October 27th, NSIT began receiving reports of isolated problems logging in to the University VPN. The problem was tracked to a missing attribute on the users' CNetIDs. Further investigation revealed that approximately 10% of our users were incorrectly missing this attribute. The root cause of the problem was corrupted data in the database managing the VPN access group. As of 6:15 PM, this corruption has been cleaned out, correct information restored, and all eligible users can once again access the VPN.

At approximately 2 PM Tuesday, 27 October, a cache problem on one of these servers caused incoming messages routed through that server to be returned to their senders. As of 5:15 PM, the cache problem has been cleared, and normal email delivery has been restored. This problem was unrelated to problems some users are having logging on to the VPN; NSIT staff are still working on that issue.

The issue has been traced to a missing attribute on the users' CNetIDs; further investigation suggests that this attribute is missing for around 10% of our users. NSIT staff are currently working to restore this attribute and normal VPN access. This problem is unrelated to ongoing problems with email delivery to @uchicago.edu addresses.

The problem has been traced to one of the three incoming email servers we have in rotation, and NSIT staff is currently working to resolve the issue.

An automated backup system erroneously began backing-up the storage system for one of the backend mail systems, which degraded the performance for users on that system. NSIT Systems Engineers cancelled the erroneous backup job at approximately 1:45PM. The impacted mail system has cleared its backlog and resumed normal operation.

An automated backup system erroneously began backing-up the storage system for one of the backend mail systems, which degraded the performance for users on that system. NSIT Systems Engineers cancelled the erroneous backup job at approximately 1:45PM. Individuals may experience degraded performance as the impacted mail system returns to normal operation.

This tends to take the form of long delays or hangs when logging in or accessing email for some, but not all users. NSIT Systems Engineers are investigating the issue and we will post more information as it becomes available.

As a result, Chalk was unavailable for most of the day Sunday while NSIT staff attempted to recover the drive; in the end, they were forced to reformat and restore from the Friday night backup. As of 11:15 PM, Chalk is once again fully functional. Files uploaded on Saturday will need to be re-uploaded; other changes (e.g. forum postings or tests/surveys) should be fine, as they would not have been on the affected drive.
