Background

VolumeSize on the block device mapping spec in MAPA is currently optional (and if is not set we send an empty value to AWS and let it choose for us), where it is required and a minimum of 8gb in CAPA.

We need to determine an appropriate behaviour for when the value is unset.

Steps

• Check historically on the installer to see what value it typically has set (in the AMI, and if that changed overtime)
• Determine an appropriate minimum size for the root volume in OpenShift
• When not set, default the CAPA volume size to an appropriate value based on the above
• Adjust conversion logic based on the above

Stakeholders

• Cluster Infra

Definition of Done

• Machines with no volume size in MAPI can be converted to CAPI
