NOTE: This command will run on Ubuntu 9.10 and higher
Once you install the vmfs-tool then you can create a folder in "/mnt/nas" and the assuming that there is a drive located at "/dev/sdb1"
apt-get install vmfs-tools
Now you can mount the drive with this command
You will need to change the fstab so it will mount on boot as well. Check my other blog posting for that and the iSCSI information. [I will update this soon with the fstab commands]
vmfs-fuse /dev/sdb1 /mnt/nas
Found some more information online for VMFS tools. Not sure how to use these command once installed. I recommend upgrading to Ubuntu 9.10 or higher.
apt-get install open-vm-source
apt-get install open-vm-tools
