parallelCluster Manager 3.2.0 failed on PERSISTENT_2 Lustre creation

[cyberchip-wang]

parallelCluster Manager 3.2.0 created with https://www.hpcworkshops.com/03-deploy-pcm/01-deploy-pcm.html does not propagate PerUnitStorageThroughput to the final Cluster Configuration. This caused the "Dry Run" failed. The workaround is adding a line manually to the Cluster Configuration template file: PerUnitStorageThroughput: 125

Screenshots:

The Lustre section in the Cluster Configuration:
SharedStorage:

Name: FsxLustre0
StorageType: FsxLustre
MountDir: /shared
FsxLustreSettings:
StorageCapacity: 1200
DeploymentType: PERSISTENT_2
DataCompressionType: LZ4
Dry Run error:

Invalid cluster configuration.
ValidationErrors:
FsxPersistentOptionsValidator: Per unit storage throughput must be specified when deployment type is PERSISTENT_2.

The issue can be reproduced by following the instructions from hpcworkshops:

Thanks for pointing out this issue, we'll fix it asap. Until then you can add a line to the very bottom indented to the same level as DataCompressionType:

PerUnitStorageThroughput = 125
