1. you will need to restart slurmctld when you make changes to the
physical definition of a node. This can be done without affecting
2. You can have a node in more than one partition. That will not hurt
anything. Jobs are allocated to nodes, not partitions, the partition is
used to determine which node(s) and filter/order jobs. You should add
the node to the new partition, but also leave it in the 'test'
partition. If you are looking to remove the 'test' partition, set it to
down and once all the running jobs that are in it finish, then remove it.
