36G 6.9G 30G 19% /
/dev/sda1 190M 19M 162M 11% /boot
tmpfs 125M 0 125M 0% /dev/shm
obviously, the root partition is not sda2 but /dev/mapper/VolGroup00-LogVol00
tmpfs is a virtual partition in your RAM
df -h doesn't say anything about sda2, but maybe df -ha will do (if sda2 is formatted)
anything i can help with?
