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.
