Resize BTRFS

btrfs filesystem resize -500m/g [mount point]

Check partition first and calc space

May ask to optimise

e2fsck -f /dev/sdaX

Check minimum size filesystem can be shrank too

resize2fs -P /dev/sdaX

Use resize2fs to safetly shrink the fs, it will move data if needed

resize2fs /dev/sdaX "the goal size"G

To automatically shrink the fs to minimum

resize2fs -M /dev/sdaX
