I tough I could check Inodes usage, but Busybox doesn’t support that. Any tipps?

umount the disk and fschk /dev/sda1

Sorry, filesystem is btrfs

Rather than df it’s more accurate to use directly btrfs fi df /mnt/sda1. Free space isn’t really a simple concept with COW sharing; it might be e.g. subvolumes taking all space, if you use those.

You must not connect a different mount point to this medium when you activate "Storage ". There was even a repeated disconnection /sda1/. Umnount sda1 and change all path settings to /srv/…
