I built a system like this (even to the extent of having /usr/src on UFS) for that reason. My experience has been that the gmirrored UFS has caused more data-related problems than ZFS (ZFS has been responsible for more hangs and panics but survives them far better and ZFS in recent 8-stable has fixed those problems). In particular, it looks like I'm losing writes to one of the disks in my gmirror (and they are identical disks, though with different firmware) under some circumstances on shutdown. I'm in the process of rebuilding that system and, based on my experiences with that system and some other ZFS root systems, will be converting it to use ZFS root. --=20 Peter Jeremy --GRPZ8SYKNexpdSJ7 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.15 (FreeBSD) iEYEARECAAYFAky/XzIACgkQ/opHv/APuIc0cACdG3rm/D4Ne87gIzptH0jz5Cfw 2ocAnA/CS2+90GRuA0JaN+KCYJ2i/JRI =+Xj+ -----END PGP SIGNATURE----- --GRPZ8SYKNexpdSJ7--
