Thanks. It seems EnforcePartLimits=ANY is what I need:
If set to "ANY" a job must satisfy any of the requested partitions to be 

Probably it got changed by who reinstalled the cluster and I didn't 
notice :(

And Slurm was doing what it's been told to do. As usual :)

Tks again

The slurm.conf web page doesn't indicate that it affects the actual queuing decision, just whether or not a job that will never run (at all, or just on some of the listed partitions) can be submitted.  If it does help then I think that the slurm.conf description is misleading.
