I am running Mandrake 10 (kernel 2.6.3-7mdk) with a 46GB / partition. This machine was given to me as is and has turned out to be/is a real trooper so repartitioning it is almost completely out of the question although I fully understand that having a single partition for the entire system (except for /boot and swap) is not desireable. The problem seems to be that the system is factoring in the /mnt partition when figuring out the disk space usage. Below you will see the output of the 'du' and 'df' commands and while I have read that df has some issues, the system does in fact say that it is running out of space when I create an iso image roughly 4GB in size since mkisofs complains that there no space left on the device. My / partition is really 14GB filled and my /mnt partition has 28GB through mounting of two windows partitions and an external hard drive. Any solutions to this? Is there a way to make it so the system does not count /mnt when figuring out disk space? Any suggestions are very welcome since my backups are failing.
