Then, after having my system running to create zfs > mirror from ad4s2 and ad5s2? Why not go ZFS all the way? ZFS on root is well supported these days (well, not by sysinstall, but it works great if you do it manually) - you don't even need UFS /boot anymore. Again, not familiar with gmirror, but my guess (that will be corrected or confirmed by someone ;) is that your way would work too. Regards, Thomas
