We're proud to introduce a new Red Hat Access Labs app: File System Layout Calculator.

To create file systems on multi-disk RAID arrays, you need to use the mkfs command with proper arguments. You need to carefully calculate the value for arguments like stride and stripe-width to make sure that your file systems align with the underlying RAID arrays and that you have maximized performance.

This app is designed to save you the trouble of making tedious and error-prone calculations by creating the mkfs command that is right for your environment. When you enter information about your current or planned storage, we'll generate a mkfs command with optimal arguments to create a file system on that given RAID storage.

Below is a screenshot of the app, but try it for yourself here and have fun. And don't forget to let us know what you think! You can leave comments on the app info page.
