How do I resize (specifically increase) the disk size of a Fedora guest VM running under VMWare ESXi 4.1?

I have a Fedora 16 VM with an ext4 formatted disk, and I've increased its disk size using the vSphere client from 50GB to about 250GB. I rebooted the guest, and it correctly shows this size using fdisk -l /dev/sda. However, df -H still shows the old size.

I've found a few KB articles explaining how to resize partitions for some flavors of Linux, but nothing for Fedora with ext4. That article seems to imply I have to create a completely new partition, and that I can't simply expand the existing partition. Using Gparted, it also prevents me from simply resizing the existing partition. Is this impossible to do under Linux?

VMWare ESXi, change the default path for a VM

For some reason VMWare ESXi has decided that one of my VMs is on a completely different path to the path it is actually on.

I'm almost embarrassed to ask this, but I'm stuck. I installed VMWare ESXi on a Mac Pro. It's working great! The problem is that you press F12 to eject the disk, and F12 is what you use to shutdown ESX. I can power down, open the case, pull out the CD drive and use a paper clip to force the drawer… >>> More
