December 28th Shutdown

by

IMAP/mail, home/project, Windows services (AD/WINS/printing), LDAP/NIS/DNS, DHCP and most other IDSG and IMG services will be affected. We will try to keep some basic network services running (DHCP, DNS/NIS), possibly in a reduced capacity.

While EECS-Secure, EECS-Guest and EECS-Open wireless LANS will be out of service during this time, the EECS and AirBears wireless LANS will remain operational during the outage.

The reason for this extended downtime is multi fold. The first is to repair the UPS that failed a couple of weeks back. The repaired unit will be placed back on line and extensive testing must be done to ensure it’s operation before we can depend on the UPS again. The second is to move data around which will allow us to remove from service a piece of software used to manage storage. This software is no longer under development and we need to remove our dependency on it. Lastly, some routine maintenance will be done which can only be done when systems are down. These are the kind of things that can only be done between semesters and we ask for you understanding during this disruption in service.

While the stated outage is from 10:00AM to 9:00PM, it may not take that long. This is a worst case scenario. If possible, services will be brought up sooner than 9:00 PM.

EECS Website, Mailing Lists and IM services down since 10:30PM

by

Starting around 10:30PM tonight, the EECS website, Mailing List and IM services (aka www.eecs, lists.eecs and Jabber) went down due to a problem with EECS Storage.

While EECS Storage is back up and most affected services — including access to home directories, project storage, Software Warehouse, and IMAP — recovered, Maillists and IM stayed down due to a backend database server that had not yet recovered from the storage outage. The Xen cluster that provides these services lost all contact with the SAN and and to be restarted.

Staff are working now to bring these remaining services back up.

In the meanwhile, if you are still having problems accessing your home directory, project storage, Software Warehouse, or IMAP, please contact the EECS Helpdesk.

Department website, mailing lists, jabber offline

by

The department’s web server (www.eecs & www.cs), mailing list server (lists.eecs), and jabber server (jabber.eecs) all run on a Xen virtual cluster. After last night’s network failure was resolved around 2:30am, the Xen cluster failed to recover gracefully. These services had to be manually restarted this morning. Web and mailing list services were restored around 9:20am, and jabber was restored around 9:45am.

Staff are investigating why this occurred and how to prevent it from happening again.
