I've noticed that there is a huge difference in free disk space for root by using "ncdu" or "df" for me:



df -Th:



    dev              devtmpfs  7,8G       0  7,8G    0% /dev
run tmpfs 7,8G 1,4M 7,8G 1% /run
/dev/nvme0n1p2 ext4 25G 19G 4,3G 82% /
tmpfs tmpfs 7,8G 77M 7,7G 1% /dev/shm
tmpfs tmpfs 7,8G 0 7,8G 0% /sys/fs/cgroup
tmpfs tmpfs 7,8G 50M 7,7G 1% /tmp
/dev/loop1 squashfs 4,3M 4,3M 0 100% /var/lib/snapd/snap/ngrok/11
/dev/loop0 squashfs 91M 91M 0 100% /var/lib/snapd/snap/core/6405
/dev/nvme0n1p1 vfat 246M 56M 191M 23% /boot
/dev/mapper/home ext4 428G 52G 354G 13% /home
tmpfs tmpfs 1,6G 20K 1,6G 1% /run/user/


ncdu



10,5 GiB [##        ] /usr
3,5 GiB [ ] /var
72,0 MiB [ ] /opt
55,1 MiB [ ] /boot
45,9 MiB [ ] /tmp


"ndcu" shows around 5.5gb more free space for root compared to "df". Am I missing something or why the big difference? Thanks in advance!
