Readynas Snapshot usage

Hey together,

 

 Attention - I'm not responsible if you damage your NAS. This is not a built in function.

 

Just had again the problem that I'd like to know which snapshot is consuming a lot of space, because sometimes it is so hard to know where, and if it makes sense.

 

Found this script here: https://ownyourbits.com/2017/12/06/check-disk-space-of-your-btrfs-snapshots-with-btrfs-du/

 

 

wget https://raw.githubusercontent.com/nachoparker/btrfs-du/master/btrfs-du -O /usr/local/sbin/btrfs-du
chmod +x /usr/local/sbin/btrfs-du

runned the script on my btrfs volume like:

 

 

btrfs-du /data/

 

actually it seems like it could be working. (at least after the change: https://github.com/nachoparker/btrfs-du/issues/9#issuecomment-380427001 ). But I have to verify a little more.

Perhaps some people here, which are knowing readynas better than me would also take an eye on it?
