Hi Christian,

> You should be able to promote the ressources using "drbdadm primary xxx" with "xxx" being the name of the ressource. (I think you have to promote them one by one.) See http://drbd.linbit.com/users-guide-8.4/s-switch-resource-roles.html  for an explanation.
> Normally, devices should be promoted when DRBD is started. Check if "become-primary-on" is set in your ressource configuration (e.g. /etc/drbd.d/foo.res). If you use some cluster management software, it should handle promotion and demotion of DRBD devices.

You're right, how did I miss that ???

I owe you a beer (or two packs of) the next time you come to Paris ;-)

Thanks a lot !!!
