Just found a handy table listing the pool version for each implementation
at Wikipedia (where else? ;-)):
>From what's listed there, seems zfs-fuse (which would be my first try for
any recovery) is still stuck at version #23 which is odd because I
distinctly remember seeing it with version 26; perhaps the table
information is outdated and/or wrong...

Do you know whether that's compatible with Illumos and FreeBSD?
