Reconfiguring the login node

[fdmalone]

Is it possible to reconfigure a running cluster to change the machine type of the login node (say from a n2-standard-2 to something else)?

I've noticed when reconfiguring a running cluster the ip address of the login node changes, is it possible to have this fixed so I don't have to update my known hosts when ssh-ing in?

Thanks!

Yes, you can reconfigure a running cluster to change machine type on the login node.

For fixed ip address, have you tried static_ip in login node ? you can specify using https://github.com/GoogleCloudPlatform/hpc-toolkit/blob/main/community/modules/scheduler/schedmd-slurm-gcp-v6-login/variables.tf#L96.
