I recently ran into the problem that / was 100% occupied. I would like to extend this partition using the remaining space on my SD card.
I’ve tried a few things but so far nothing worked out for me. http://elinux.org/RPi_Resize_Flash_Partitions#Manually_resizing_the_SD_card_using_a_GUI_on_Linux failed using gparted in Fedora 21. This one http://elinux.org/RPi_Resize_Flash_Partitions#Manually_resizing_the_SD_card_on_Raspberry_Pi also failed.
I know that it would be interesting to see the log of boot sequence but that would require a TV/monitor which I don’t have. Any ideas what usually fails during resizing?
