Scheduled Maintenance

This page is being updated.

Upgrade of machines 2017

Machines to upgrade: 30


  • Main reason is to avoid security holes and update libraries.
  • Libraries not present in the distribution will be provided with a new mechanism implemented with success by Lunarc. It will be in a test state during 2017.
  • OpenSuse 13.1 is out of support since November 2016; the software is already old.

Target distribution

  • Ubuntu 16.04 will be supported until 2021 and is my preference. There will be no more machine update until that time.
  • OpenSuSE Leap can be installed upon request. Its release cycle and support is unclear, therefore I am not supporting it anymore.

Tentative Schedule

Status of other machines

Papaya will be updated to a more powerful machine running centos7. It will run all services on a raid 1 sw disk set.

  • nis master
  • cups print server
  • mathematica license
  • intel license (if matfys buys a new one)

Upgrade of vespa 2017

Decision pending: centos6 or centos7

From :

CentOS6 CentOS7
Full Updates Q2 2017 Q4 2020
Maintenance Updates November 30th, 2020 June 30th, 2024

Probably CentOS7 for all machines is the best choice.


  1. Update to a new machine with CentOS7
    • define salt states for it
    • install intel license server
    • install salt?
    • install tftp
    • install needed pxe boot stuff for nodes
    • %DATE% Switch old vespa frontend to new vespa frontend
  2. Update n3 as guinea pig
    • %DATE% switch off n3
    • define salt config states
    • install slurm
    • test slurm interactive mode
    • install eb
    • install modules: new env must be completely based on modules, no more specific

front ends

  • will be changed to a newer machine
  • the system will be updated

old nodes n1-n5


old nodes n6-n10

Opteron! Will CentOS7 run on those? Test on n6

old nodes n11-n12

new nodes n13-n20

  • no planned update at the moment. They run CentOS6.x and easybuild.
