Hi all, When having a non-btrfs fs and want to migrate to btrfs, it is hard to know which sector size to choose in terms of disk utilization and speed.
So I would like to make a script that scans the non-btrfs fs's directory structure to find all file sizes and calculate how much space these would take on btrfs 4k and 16k sector size. Can anyone help me with a formulae to calculate this for a file? It doesn't have to be exact, just enough to make a decision between 4k and 16k.
