EXT4 And Storagenode Free Space & Optimization

[Toyoo]

What is the best percent for overhead space?

I had it very close, below 5 GB of free space on a 5.5TB volume. That was, uh, kinda an accident. Fragmentation started showing up, but except for that, it was working well. Though given the code is still young, I wouldn’t recommend it either, bugs may happen.

There seem to be several reasons why they advice the 10%:

One more reason: to account for file system overhead, which is not easy to measure. This includes things like cluster size, file metadata storage.
