Hello all,

Is there any way how to obtain information how much space is
physically allocated by given subvolume?
I cannot find any. I'm interested in two values:

- physical space allocated by SUBVOLUME INCLUDING all space shared b=

y

quoted

other subvolumes

That's the space reported by `du -hs /mnt/btrfs/subvolume`

it should be `du -hsx /mnt/btrfs/subvolume`
but what if there are reflinked/CoW files inside this subvolume?

y

That's not implemented right now

Currently I can use only du, which is not reporting what I want to k=

now.
