Supporting RH5 and RH6 for Control and Correlator
ALMA 2015.8 - will be moving to RH6 in Dec 2015
Should move to RH6 before that in the CV STE
A certain version of ACS and intlist
So the STE would be in a permanent state of RH6, but the diskless machines could boot to RH5
An environment to run Cycle 3 software in RH5, for testing and debugging
Multiple users, in different environments, simultaneously on the CV STE
Alexis believes it is doable, but will take some time
Rachel suggestion: can we keep some of the machines permanently as RH5 machines? Are there enough?
Alexis suggests that there be a RH6 machine which hosts a RH5 VM.
Rodrigo agrees this is the way to go.
What about an official image of RH6? We don't have one, as far as we know
Use GIS as the place to test the installation of RH6
Testing on one machine ~1 week
Getting things running operationally ~2-3 weeks
Basically running one STE at RH5 (hold it back from upgrading, run Cycle 3 software on it for roughly the next 12 months), the other STE could be moved to RH6 for test team testing
Move the chosen STE to RH6 in December 2015/Jan 2016
Ralph does not necessarily need an RH6 STE, so for him the priority is to keep an STE at RH5
Find an initial RH6 image to be used. (Andy to contact Tzu)
Pick the test machine at the NTC (GIS) to be used to install RH6 on (Rodrigo)
in my view the good candidates are gas03 and gas04. They do not have a very specific role at this moment within the STE. They both are:
Dual Core AMD Opteron(tm) Processor 275
4 GB RAM
20 GB Hard Disk (at this moment 2.6.18-194.32.1.el5PAE)
Get a RH6 image by Sept 11th, for correlator testing
Get a RH 6 test machine up and running for pre-testing (GIS machine) by Sept 18th
This entails having RH6 hosting RH5 VM, and be able to remotely boot
Ensure that the STE in Socorro that will be held back has a regularly updated copy of the cycle 3 software by Oct 5th.
