When I do a
btrfs filesystem defragment -r /directory
does it defragment really all files in this directory tree, even if it
contains subvolumes?
The man page does not mention subvolumes on this topic.
I have an older script (written by myself) which does a
"btrfs filesystem defragment -r" on all subvolumes recursivly:
btrfs filesystem defragment -r $m
for s in $(btrfs subvolume list $m | awk '{ print $NF }'); do
[[ "$s" =~ ^@ ]] && continue
[[ $(btrfs subvolume show $m/$s) =~ Flags:.*readonly ]] && continue
btrfs filesystem defragment -r $m/$s
done
I wonder why I have done it that way :-}
