From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

When you create a filesystem, there is a parameter named as "block percent free". This parameter should be "5%", so a 5% of your partition size can only be written by the "root" user.
You can decrease this value or just free some space. You can try to create files or folders as root as well.
Is there any reason this 5% number still holds true? Back in the days of 40 MB hard drives it made sense to make sure the system didn’t totally run out while root was fixing the low disk situation … but these days even 1% is still several gigabytes of space, not likely to run out that quickly.

Fragmentation probably but seems arbitrary
Are you sure that's the case with btrfs? I know ext has that feature. My understanding is btrfs just has a global reserve that can be used for any data in an low space situation.
You/I learn something new every day. Cool info!
