That's right, use mv for the first step.  Then you:
   * create the new volume
   * mount it as dir2
   * use "up" to copy the original dir2's contents -- including 
subdirectories and the ACLs burried therein -- to the new dir2.

I thought the original problem was to keep the directory structure and 
ACLs as they were, but to turn the dir2 directory into a mountpoint for 
a new volume.  Unless I'm missing something, the above steps are the 
easiest way to do that.
