I'm trying to follow the Parallel Cluster tutorial and pcluster create-cluster failed. The reason, per pcluster get-cluster-stack-events:

Amazon FSx does not currently support Lustre file system creation in the following Availability Zones: ap-northeast-1c (Service: AmazonFSx; Status Code: 400; Error Code: BadRequest; Request ID: ....; Proxy: null)

I never specified ap-northeast-1c — everything in my config refers just to ap-northeast-1 (i.e. Asia Pacific (Tokyo) region). And checking the AWS Regional Services List though, "Amazon FSx for Lustre" is listed as available.

I have no idea why it failed, or how to fix it. Any ideas?

I figured it out: ap-northeast-1c is determined by subnet, which the tutorial picks at random. While ap-northeast-1 region does support Lustre file system, not every availability zone does; using the subnet that corresponds to ap-northeast-1a solved the problem.
