Hi,
I am for the first time trying the resize option in elasticluster.
I got a new elasticluster from github today.
This is the only template I have
(elasticluster_07052019)[centos@elasticluster-final ~]$ elasticluster list-
templates
1 cluster templates found in configuration file.

name: slurm
frontend nodes: 1
compute nodes: 7
And this is what I get if I try to expand with 2 compute nodes
1) is it correct to use "compute" to name the group - I am not sure if I
should chose compute_node which is what I have in my configuration file, or
compute or slurm_worker that I see in my inventory file
2) What is the error below due to?
(elasticluster_07052019)[centos@elasticluster-final ~]$ elasticluster
