Are there any real advantages of ext4 over ext2 ?

I had a similar use-case with zfs-fuse on Debian GNU/Linux several years 
ago.  I recall writing an import script that ran during system startup 
and an export script that ran during system shutdown.  This was prior to 
systemd and fairly easy to do.


But, I have also used the force '-f' option for various zpool(8) 
commands more often than I care to admit.  ;-)
