Does FSx for OpenZFS allow updating SSD storage capacity after creation?

The SSD storage capacity of Amazon FSx for OpenZFS file systems is immutable post file system creation and only supports intra file system origin snapshot transfers. The recommended path to have more SSD storage capacity is to create a new file system with greater SSD storage capacity and copy the files over using standard Linux copy tools, like rsync, fpsync, mcp, etc. Throughput capacity can be updated post file system creation, so make sure both file systems have adequate throughput capacity. The EC2 instance used to copy files from file system to file system should have high network performance (e.g. network optimized instances like c5n, c6gn, etc.) and the Linux kernel should be 5.3 or later. Both file systems should be mounted using NFSv3 using the nconnect=16 mount option. The nconnect mount option is available on Linux kernel 5.3 and later and will establish multiple TCP connections from the EC2 instance to the FSx for OpenZFS file system, allowing for optimal throughput. See the performance section of the FSx for OpenZFS User Guide for more tips on maximizing performance - https://docs.aws.amazon.com/fsx/latest/OpenZFSGuide/performance.html#performance-tips-zfs.
