Scheduled Maintenance

Upgrade of machines 2014

Machines to upgrade: 56

Reasons: Main reason is to avoid security holes and update libraries. Since updating libraries might cause issues when using existing code, a set of machines with a specific version of the OS can be maintained to prevent and cross check compilation issues. Further information in Situation and Selection criterias

Tentative Schedule

NOTE: The expected update time for each machine is between 2 and 3 hours.

Selection criterias

  1. Target upgrade is to OpenSuSE 13.1 for two reasons:
    1. It seems to have the most up-to-date libraries that suit most needs
    2. Evergreen support has been announced until November 2016, see https://en.opensuse.org/openSUSE:Evergreen
  2. Machines with OpenSuse 11.2 must be updated first. Support stopped 2013, see https://en.opensuse.org/openSUSE:Evergreen
    1. Some OpenSuse 11.2 machines will be left to avoid compilation issues, so that users can still have the same environment
    2. Machines will be selected in a way that there is at least an old machine with the same memory/processor for each updated one.
  3. Machines with OpenSuse 11.4 will be updated next. Support stopped July 2014 (https://en.opensuse.org/openSUSE:Evergreen)
    1. See selection criterias above.
  4. Servers will be updated last, from the least to the most important.
    1. The most important ones will be updated after the other machines. A special schedule will follow as it will affect everybody.
