Also, you might want to look at the "up" utility to copy the contents of 
the original dir2 into the new volume, especially if you have lots of 
complicated ACLs burried down in that subtree.  Up is sort of a 
recursive cp that also knows about and duplicates ACLs.  It's obvious 
when you think about it, but to use "up" effectively, you must have 
sufficient read rights to all the data you're trying to copy.
