Which Linux Partition?

I’m trying to upgrade a system’s Grid Infrastucture to the latest/greatest version. The OUI says that I need 7GB of free space and I’m a little short.

Well the disk device is /dev/sda which is the first disk device on the system. This disk device has two partitions, named sda1 and sda2. Which partition is for the root file system?
