Slurm DB always get set as db.t4g.micro no matter what option is used #30

need bigger instances cause for large fleets this small instance db.t4g.micro is unable to respond in time when large jobs are launched

nicolaven commented 2 years ago

Absolutely, make sense. The reason why I used this instance is because it is within the free tier but feel free to set a bigger one here: https://github.com/aws-samples/1click-hpc/blob/main/Templates/AWS-HPC-Cluster.yaml#L84

rvencu commented 2 years ago

Yes, what I am saying, setting it differently still result in getting db.t4g.micro

No idea why it happens

nicolaven commented 2 years ago

so, what you are saying is that you have a different instance type in your custom CF template set accordingly to the region where you plan to deploy the new cluster, then you built a new cluster using your template and you are still getting the t4g ? (please note I fear stack updates are not supported)

Yes. It seems weird but this is what happens. For good measure I put all regions with same other instance type and still getting the t4g one

With a clean, new install

there must be something wrong, can you please hardcode the instance type, like:

DBInstanceClass: 'db.m6gd.16xlarge'

and try again

Thanks

rvencu commented 2 years ago

tested with DBInstanceClass: 'db.m6g.8xlarge' and I still get the t4g
