Hi everyone, further debugging allowed me to find the root cause.
I think there is a bug in line 1356 of the function checkdisk in subroutines: $(stat -c %G /dev/$device) = "disk" According to the manuals I found (https://man7.org/linux/man-pages/man1/stat.1.html) stat -c %G returns the group of the owner, but nothing related to a device type. Therefore reintroducing the old way of determining hard drives fixes this issue. -------------------------------------------------------------------- (SFB1170, Project Z03, part-time system administration) Interested in Research Software? https://de-rse.org/chapter/wue/ http://z03.physik.uni-wuerzburg.de (uni network) Theoretische Physik 1 Institut für theoretische Physik und Astrophysik Am Hubland, 97074 Würzburg GERMANY
