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.

New SSL certificates will be installed at 10pm tonight (Monday) on www.eecs, lists.eecs, jabber.eecs and iris.eecs.

Each of these services will be restarted between 10pm and 10:15pm tonight, Monday, December 14th, 2009. Brief outages may be noticeable, but no server should be unavailable for more than a minute or two.

Mailing List Messages Delayed

by

The Department’s mailing list server, lists.eecs.berkeley.edu, ran out of memory last night around 12:45am. The service was restarted at 8:45am, and all delayed email has now been delivered.

More memory has recently been purchased and installed. The server will be reconfigured later this week to use the new memory. We hope this will resolve this problem.

Mailing List Web Interface down

by

The web interface to the Department’s mailing list server lists.eecs.berkeley.edu is unavailable. There is a problem authenticating against our LDAP servers over SSL. This problem is currently being investigated, and we hope to have the web server available soon.

Mail delivery to lists hosted on lists.eecs is not affected. No mail has been delayed or lost.

If you need assistance managing your list during this outage, please send your requests to help@eecs and staff will make them for you.

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.
