[Solved] Power failure in the serverroom

Added by Carsten Rose over 8 years ago

During the evening we had a power failure in the serverroom. The I-MATH cloud was unaccessible: thinlinc, ssh, edx. All Thinlinc sessions are lost.

Duration: 1.10.2015 20:40 CEST - 2.10.2015 08:30 CEST

  • One fuse has switched off and a connected network switch stops working. The storage for the I-MATH cloud are connected via this network switch and therefore the whole I-MATH cloud stopped working.
  • To resolve the broken storage connection, a complete reboot of all VM of the I-MATH cloud was necessary.
  • The mailserver and the webserver are not affected, cause they use a local storage.
  • With the next maintenance date 21.10.15, we will rearrange the power distribution as well as reconnecting all I-MATH netwoork switches to a USV.
  • Notifcation of the malfunction has been automatically reported (just in time) - unfortunately the receiving mobile phone was 'muted' and the alarm not recognized at the evening.

[Solved] Problems with new thinlinc server tl15/16

Added by Carsten Rose over 8 years ago

During the day we encountered different problems with the two new thinlinc servers tl15 and tl16.
The main problem was 'no access from outside of the institute' - multiple firewall and ssh configurations issues caused this.
We apologize for the trouble.


[Solved] Institute offline 1.10.15, 13:50-13:58

Added by Carsten Rose over 8 years ago

A technician removed accidently a power cable from a main network switch in our server room - the institute has been 8 minute offline: no web, mail, thinlinc.
Now, everything should be normal again.

The work in the server room is related to 'VoIP preparation' on 21.10.15.

Sorry for the trouble.

All Thinlinc sessions now start a small applet in the upper right corner to display the latest I-MATH IT News.

The icon starts blinking as soon as a new message arrives.

[New] All wikis in UZH CD layout

Added by Benjamin Baer over 8 years ago

We updated all of our wikis from the 'moin moin' standard design to a more UZH CD friendly look.

To make it more clear that the wikis are hosted inside the institute, we incorporated a more UZH CD friendly design for all of our internal and public wikis.

We also changed the message 'you do not have permission to view this site' to be more clear that you should login to the wiki first. The standard message was confusing and didn't point you to where you could login.
