I want to check my file usage with programs like https://wiki.ubuntuusers.de/Festplattenbelegung/ for the files on my partitions on which / (root) is on. However, there are many other files systems mounted into the file system somewhere. Those I do not want to check out - only my root partition. How can I exclude those? I would like to use a GUI program (so not du). I thought that I either find a program in which can do the exclusion, but I haven't found one. I thought another option might be if I could mount my root device (/dev/mapper/mylvg-myrootpartition) to another location additionally to the normal mount to / and analyse this second mount folder, but I haven't managed to do that. Ideas?
Analyse disk usage for root partition excluding other partitions that are mounted with GUI program?
