resize fsx share #1346

Open karlvirgil opened 4 years ago

karlvirgil commented 4 years ago

Environment:

Bug description and how to reproduce: I have an /fsx share that was created when I created my pcluster instance. I would like to resize that share to be double the current size. Can I do this? What is the best way?

According to FSx Lustre docs:

The size and performance of your file system is determined when you create the file system. Once a file system is created the total provisioned size cannot be changed.

What you could do is to use the export_path configured with the existing FSx to upload the entire content to s3 and then create a new file system that uses that export_path as import_path. Additional details: https://docs.aws.amazon.com/fsx/latest/LustreGuide/fsx-data-repositories.html

Once you have that either you create a new cluster with the new file system or if the described flow works for you I can verify if updating the config of the existing cluster is compatible with this change. In any case all cluster nodes would require a replacement.

Makes sense. Thanks.

Hi @karlvirgil & @demartinofra, Amazon FSx for Lustre recently launched support for increasing the storage capacity of file systems with a click of a button. More info is available on the What's New page.
