FS / inode / vnode refresher

A vnode is an inode with a hostid prepended.

But you should only need to know this if you are writing NFS code. 
Otherwise it's overkill. It has absolutely no bearing upon your capacity 
to administer NFS. There is no nfsck(8) (cute, eh?). Where the rubber 
meets the road, it's all inodes.
