Hi again Shkelzen,
Here is what is in my log :
--french----------------------------------------------------------------
Reconfiguration des workers nanpcw1 à nanpcw15. Profile copié avant
arrêt mais dépendance SPMA bloque le composant ncm-network = blocage et
intervention manuelle. Mise en prod.
Reconfiguration des workers nanpcw16 à nanpcw33. Profile copié avant
arrêt et forcé le composant ncm-spma avec l'arrêt. Méthode correcte, les
workers sont presque utilisables après le démarrage...
Avant l'arrêt :
slnrsh ferme8 '/usr/sbin/ccm-fetch -f;/usr/sbin/ncm-ncd \
--configure spma;/sbin/shutdown -h now''
------------------------------------------------------------------------
Comment 1 : What is missing is that I probably disabled (stop)
ncm-cdispd on the worker nodes to prevent them from starting ncm
complete reconfiguration with the new IP. Still running with their old
IP, they should get their new profile (ccm-fetch) and you ensure that
only spma runs, then shutdown. They will run ncm at startup
on the new network and configure their new IP then.
slnrsh is a local tool to run a command on all workers.
Comment 2 : the reason to have spma run before shutting down is that
it blocks the new IP configuration if it fails. So, better ensure that
you got all needed packages before.
Hope it helps. Sorry if it is not very accurate, I was somewhat short
on the details in my original log.
JM
