Few things:
- you don't need fstab entry for ZFS
- make sure you have zfs_enable="YES" in /etc/rc.conf
- make sure (perhaps this is your issue) /boot/zfs/zpool.cache is
  writable. This is where ZFS remembers (among many things) what you
  had previously imported. BTW why your /boot is ext2?
- check that "zfs get canmount home" returns "on"
