There may be some disruption of services at 1cc this week due to the announced MIT Media Lab upgrades. At the moment we have no DHCP services at 1cc.
--HH. ---------- Forwarded message ---------- From: Jon Ferguson <[EMAIL PROTECTED]> Date: Fri, Aug 22, 2008 at 5:22 PM Subject: [outages] Major file system outages and ML upgrade next week To: [EMAIL PROTECTED] Hi all, In addition to the outages this weekend (while we rearrange our machine room), we will also be upgrading our central file server file.media.mit.edu (and its sidekick dell3.media.mit.edu) next week. While this service interruption will be less major in scope than the ones this weekend, it will still affect many systems here at the Lab. It also needs to be done during a weekday so that we can have the expert, on-site assistance of the file system software vendor. The outage will happen either next Thursday, August 28, or possibly next Wednesday, August 27 (it depends on the availability of the file system expert). Plan for Thursday and we'll let you know as soon as possible if it becomes Wednesday. During the outage everyone's central Unix home directories, and machines such as hub.media.mit.edu, ml.media.mit.edu, and file.media.mit.edu (including any file shares they serve like machub and winhub), will be unavailable. People's personal Web sites served by web.media.mit.edu will also be unavailable. The outage will start in the late afternoon around 3pm or so and will continue all night. Everything should be back online before the next morning. Email and general network access will be unaffected. There is a much less used file server, dell3.media.mit.edu, which will go offline the day *before* the file.media.mit.edu outage. This should only affect a small number of people who use this server to mount the /mas tree under special circumstances in order to work around compatibility problems with using file.media.mit.edu directly. This is mainly Mac OS X people who have configured the automounter to provide access to the /mas tree (and they should know who they are). Also during this time we will be taking the opportunity to upgrade ml.media.mit.edu. This will involve a significant upgrade to ml's hardware and operating system. Currently, ml.media.mit.edu is an AlphsServer DS20 running Tru64 UNIX v4.0G. It will be replaced by a Dell PowerEdge running Linux. Email, ssh, and ftp services will work as they do now, and the upgrade brings with it newer versions of many utilities and packages. However, in the event you have compiled some Tru64 (aka Digital UNIX) binaries for use on ml, they, of course, will no longer work. Our apologies for any inconvenience as we try to fit in all these infrastructure upgrades before the start of the semester. Please alert us to any problems this may cause so we can work out solutions as quickly as possible. Cheers, NeCSys If you have questions, problems, comments, etc, send them to [EMAIL PROTECTED] Thanks!
