I actually don't use snapshots on it.  All the data that shows up in
/storage2 
is gone from /storage as far as I can see.  This was a simple highlight
many
directories and then move function in midnight commander.  Nothing exotic 
except for how much data was being done.  This is a very simple pool,
nothing
fancy all default, just a file dump for the most part.  I can't figure out
how
to recover the data, a scrub locked the pool randomly, no error, just can't
get
in or ctrl-c/z the ls.  It only happens on /storage which is why I wanted
to 
first test moving things out to /storage2 to see if that made a difference.
