[Mauiusers] Re: reserving nodes to a particular queue

Hello Jerry

Thanks for the answer. That was the missing piece.

  SRCFG[new] PERIOD=INFINITY HOSTLIST=new[123] CLASSLIST=new

This will set up a reservation so that only jobs in queue 'new' will be
allowed to use the new nodes. So far, so good.

However jobs in the 'new' queue can still use the old nodes if they are
available. I could set up reservations for my 'old' queue to only have
access to the old nodes; i.e.

  SRCFG[old] PERIOD=INFINITY HOSTLIST=old[123456789] CLASSLIST=defaultq

This gets complicated if there are more than 2 queues and I have to add
and remove hostnames to these lists.

Is there a better way of restricting jobs in the 'new' queue to exactly
the 'new' nodes?
