 Thank you for additional detailed information.
 Could you please set vfs.zfs.debug=1 in your loader.conf and reproduce the
 problem and then report messages that appear just before and during mount attempt?
 Pictures of your screen would do just fine if you are unable to capture the
 messages as text.  If you are unsure what to report please report more rather
 than less.
