plompy terminal server: unscheduled maintenance reboot

Friday, November 4th, 2011

Today at 13:00 we had to reboot plompy, one of our LTSP terminal servers. We’re sorry for any inconvenience. In order to prevent those terminal servers from clogging up memory in the future, we hereby announce the following maintenance reboot schedule:

plompy: first Sunday of each month, 02:00 am
plimpy: third Sunday of each month, 02:00 am

There will always be one functioning terminal server and upon login your thin client will choose the right one. Please don’t forget to save your data when leaving for the weekend before those two Sunday dates (that’s always a good idea anyways).

Short downtime for plempy, plompy and plumpy on Monday Aug 2

Tuesday, July 27th, 2010

On Monday, August 2nd, starting at 07:00, our terminal server / computation nodes plempy, plompy and plumpy will be moved into the water-cooled racks in the HIT server room. This will cause a downtime of said machines of about 30 min. If your thin client connects to plompy or if you’re performing calculations on plempy or plumpy, please make sure your data has been saved by Monday morning. After the move, the trio will enjoy the amenities of our most advanced server room that only another thunderstorm could disrupt.

Update Mon Aug 2 08:40 All servers have reached their final destination.

Plimpy maintenance reboot

Friday, June 18th, 2010

Our terminal server plimpy (uptime: 47 days) is slowly clogging up with runaway processes, eating up memory and CPU. Since we cannot tell apart good processes from bad ones, we schedule a maintenance reboot for the Weekend, Saturday night June 19th in order to give the system a fresh start. We ask all users to save their data and log out of their thin clients.

BTW: Users of second generation thin clients (named tc00xx) are kindly invited to test our new ubuntu based terminal server plompy. If you’re interested to give it a try, please let us know and we will configure your client.

Plimpy maintenance reboot

Tuesday, February 23rd, 2010

Our terminal server plimpy (uptime: 80 days) is slowly clogging up with runaway processes, eating up memory and CPU. Since we cannot tell apart good processes from bad ones, we schedule a maintenance reboot for tomorrow, Wednesday February 24 at 18:00 in order to give the system a fresh start. We ask all users to save their data and log out of their thin clients. Update, 18:45: Plimpy is up and running again.

LTSP Clients And The LTSP Server “plimpy” Upgrade

Wednesday, June 17th, 2009

We will upgrade our LTSP server “plimpy” the next Wednesday, 24 June 2009 starting at 7 pm. Please save all your open documents and log out until that time. The machine should be ready again the next morning. You don’t have to back up your data on /scratch since we will do that. Find the details on the software changes here.

While performing the upgrade to Debian “lenny” we will switch to a 64 bit kernel since finally also Adobe flash player, the last missing mission-critical app, is now available for 64 bit Linux. Unfortunately Adobe still doesn’t ship 64 bit Linux versions of Adobe Reader (formerly Acrobat Reader). You can still fill Adobe Reader PDF forms and even create and edit PDF documents on the Windows RDP Server “ramora” which you can access via the ETH Zurich menu, Microsoft Office (or the full-screen login, see above link).

RAM upgrade for LTSP Terminal Server

Monday, April 6th, 2009

On Wednesday, April 8, starting around 0730 we will upgrade the RAM in plimpy, our LTSP terminal server. This will cause a downtime of about 5 min and the loss of all open sessions. Please make sure to have all your data saved by Tue evening if you’re working on a thin client.

Update Wed 0800: plimpy now has 16 gigs.
