I'm trying to mount /vol to a EBS volume on an Amazon EC2 instance. I'm formatting the device to xfs, adding "/dev/sdh /vol xfs noatime 0 0" to my /etc/fstab file, making the /vol dir and mounting it and whenever I try to do anything with that volume (create a file in /vol, cd, ls, anything) or I try to run df the server just freezes.

Anyone have any idea what this might be? It's driving me crazy.

Edit: It seems to freeze after I mount, has nothing to do with doing any commands to the volume it's self.
