How do I troubleshoot “insufficient capacity” errors that occur when I create an FSx for ONTAP file system?

Short description

If AWS doesn't currently have enough available resources to complete your request, then you receive the following InsufficientInstanceCapacity error:

"Your file system failed to create due to insufficient capacity. Please delete your file system and create a new one. To reduce the risk of encountering this problem again, try providing a subnet in a different Availability Zone or wait some time before re-creating."

Resolution

To prevent insufficient capacity errors, repeat the process to create the file system. Then, make the following changes:

• Capacity changes over a period of time. Wait a few minutes, and then run the CreateFilesystem workflow again.
• Change the throughput capacity (the default is 128 MB/s).
• Change the file system's storage capacity or size when you create the file system.
• Change the Deployment type to Multi-AZ.
• For deployments that don't have a dependency in a particular Availability Zone, choose a different subnet.
