EC2 - A volume's size associated with a node is null

[zmalik]

Recovering a node, when you see its volumes, the size is recovered as null, while the volumes occupies a space, in my case it was a 8GB standard volume.

while the other fields like following are recovered correctly.
{id=vol-4d119914, type=SAN, device=/dev/sda1, bootDevice=true, durable=true}

I'm using 1.7.0-SNAPSHOT
