Greetings!
BTRFS wiki says there is no per-subvolume compression option [1].
At the same time next command allow me to set properties per-subvolume:
btrfs property set /volume compression zstd
Corresponding get command shows distinct properties for every subvolume.
Should wiki be updated?
The wiki should be updated, but it's not technically wrong.
What the wiki is talking about is per-subvolume mount options to control
compression (so, mounting individual subvolumes from the same volume
with different `compress=` or `compress-force=` mount options), which is
not currently supported.
You are correct though that properties can be used to achieve a similar
result (compressing differently for different subvolumes.
