failing to add compute node in shared-vpc

[Hiroshi Kobayashi]

Hi everyone,

I deployed a slurm cluster via Terraform into a shared-vpc.

The cluster and the shared-vpc are hosted on separated projects.

The deployment itself looks OK. A login node and a controller node are up and running.

But when I submit a test jobs, the computing nodes were NOT coming up.

According to the api log,  failing to launch computing nodes due to unknown subnet.

status: {

code: 7

message: "Required 'compute.subnetworks.use' permission for 'projects/<projectname>/regions/us-west2/subnetworks/kobayashi-dev-us-west2'"

the subnet name "kobayashi-dev-us-west2" is not correct. My shared-vpc subnet name is given in tfvars and  it is "us-west2-prod-hpc".

"kobayashi-dev-us-west2" is combined name of the cluster name and region name.

I guess when the shared-vpc is enabled, the wrong subnet name was provided to compute-api.

Any ideas on how to fix this wrong subnet name?

Thank you,

Hiroshi Kobayashi

Hi Hiroshi,

Please make sure you fill in the "vpc_subnet" field in the partition definition with your desired subnet. Otherwise, with it set to null as it is currently, Slurm will try to create a new subnet in the network specified for that partition, and you could run into the issues you've seen here.

Let us know if that fixes the issue. We're also working on highlighting this better in the documentation.

Thanks,

Hi Wyatt,

I could resolved this issue by put the subnet name into "vpc_subnet" field in the partition definition.

Thank you so much!
