Hi all, I want resize my partition and I have already some free space. However I don't know realocate that free space (10GB). I used qtparted (with live distro) to free some space from windows, but I don't know how can I resize. from df I got: [jopa@localhost ~]$ df Filesystem 1K-blocks Used Available Use% Mounted on /dev/mapper/VolGroup00-LogVol00 6316560 5639964 350556 95% / /dev/hda2 101105 14208 81676 15% /boot /dev/shm 249576 0 249576 0% /dev/shm [jopa@localhost ~]$ Best regards, Joao.
