 If you have some "free" space on your volume, but the unallocated space is below 10% (or close to 10%), you can help btrfs to rebalance some parts.

 Btrfs looks for chunks that contain more than 50% free space. It will take 2 of them and then move everything into a new chunk. After that, a chunk is released. This continues until each chunk is at least 50% full.

 Btrfs looks for chunks that are less than 75% full.
 It will take 4 of them and then move everything into 3 new chunks. After that, a chunk can be released. This continues until each chunk is at least 75% full.
 If you still have less than 20% unallocated space, please do the following:
-{{RootCmd|command=btrfs balance start -musage=90 -dusage=90 /}}
