hmm.. you should be able to unload and load the zfs module if
everything is unmounted/exported and all the consumers of libzfs aren't
running, this includes fmd as well as zoneadm. Did you try disabling
zoneadm as well?
You can also check that all three of these variables should be zero:
zfs_active_fs_count
spa_active_count
and zvol_minors
