Changing the size of the predefined AMI's EBS volume about aws-parallelcluster HOT 4 CLOSED

Are you using the http://cfncluster.readthedocs.org/en/latest/configuration.html#master-root-volume-size option in the config? What specific version of CfnCluster are you using?

When testing a new configuration, using the --norollback option, which disables rollback and then you can usually access the instance for troubleshooting.

Hi Dougal,

Thank you for your swift response.
I am currently using the latest version [0.0.22] of cfncluster.
Indeed, by adding the options master_root_volume_size and compute_root_volume_size in my cfncluster config file solved the issue with the root volume size.

Best,
Bill

Okay, as an FYI, the typical approach I would take for your situation is setting up all the source code and input files in the /shared directory and then making an EBS snapshot from this volume. You can then easily attach this snapshot for future clusters - http://cfncluster.readthedocs.org/en/latest/configuration.html#ebs-snapshot-id.

This has the advantage that you don't need to build a custom AMI, which typically means you need to rebuild everything for newer versions of CfnCluster.

It works perfectly fine!
