It sounds like your superblocks got corrupted.  There might still be 
good file data in there but you've lost the top level directory structure.

There is a dearth of tools for recovering data from ZFS pools.

Its a very good idea to use something like copies=2 or copies=3 if you 
are using ZFS on a single disk system like a laptop!!
