No -- the on-disk format is different. ZFS will run fine with the older on-disk formats, but you won't get the full benefits without updating them. You'll need to run both 'zpool update -a' and 'zfs update -a' -- this is a non-reversible step, so be certain you will never need to downgrade before doing it. Also, you *will* need to update gptzfsboot on your drives, or you will come to a sticky end if you try and reboot. Something like this: # gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ad0 Cheers, Matthew --=20 Dr Matthew J Seaman MA, D.Phil. 7 Priory Courtyard Flat 3 PGP: http://www.infracaninophile.co.uk/pgpkey Ramsgate JID: matthew@infracaninophile.co.uk Kent, CT11 9PW --------------enigFAC1BC1AAF7B4B3CF657DCFE Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.16 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk0bdDkACgkQ8Mjk52CukIzYtgCgiqmzK5kMMqiqC3Hxg7pgLoqN QTAAniZ8vAAJplHbPEwqdhn85oSGpCeX =4wVD -----END PGP SIGNATURE----- --------------enigFAC1BC1AAF7B4B3CF657DCFE--
