Most, if not all of your problems will probably be resolved by upgrading to the new code, as found in 7.2-STABLE and 8.0. New versions of the code are backwards compatible with old on-disk formats. Should you decide to upgrade to the new on-disk format with "zfs set version=3" and "zpool upgrade," the process is documented as keeping your data intact. While it is always a good idea to back up your data before potentially-dangerous filesystem operations, I, along with many other people, have upgraded ZFS on-disk formats without issue. -Boris
