# mkdir /mnt/disk3/tst
mkdir: cannot create directory ‘tst’: No space left on device

I suspect this is BTRFS balancing issue, but even BTRFS's own utility is indicating there's still SOME space left. Certainly should be enough to create a directory.

Any ideas?

Just in general BTRFS default options for creating new volumes seem to not work well for disks that I intend to fill completely immediately after formatting. Are there better options for this use case? I just use

# mkfs.btrfs /dev/sdd1

btrfs dynamically allocates inodes.

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.
