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.

How to figure out why BTRFS drive reports it is out of space (lemmy.sdf.org)

# sudo btrfs fi df /mnt/disk3
Data, single: total=12.70TiB, used=12.27TiB
System, DUP: total=8.00MiB, used=1.34MiB
Metadata, DUP: total=15.00GiB, used=14.50GiB
GlobalReserve, single: total=512.00MiB, used=608.00KiB

# 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

Would be nice if there's some automatic solution, but after running into this issue I always run a couple different btrfs balance after deleting larger files for good measure. Took a while to figure out why Linux said there wasn't any space left when df reported several GB available on the root partition

I am surprised there isn't an automatic mechanism to handle this especially if it is such a frequent issue.
