Arrrgh!
Code:
lsblk --version lsblk from util-linux 2.33.1
Got the problem now. I develop on OpenSuse, then test on debian LnixCNC iso.
Thanks a ton, need to find another way to determine which local disc has most free space.

BB, tommy and who else might be interested:

Code:
df -l -x tmpfs | grep -v udev | sort -r -n -k4 | sed -n 1p
