Only write performance to the UFS root filesystem. I run a system using a similar approach (though across 3 disks). My only suggestion would be that instead of a single 5-way mirrored root, you have a 2- or 3-way mirrored root and an off-line root backup using the remaining disks - if you accidently trash your active root, you can just boot off one of the other disks to recover. --=20 Peter Jeremy --+Z7/5fzWRHDJ0o7Q Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.11 (FreeBSD) iEYEARECAAYFAko36eUACgkQ/opHv/APuIeeJQCfUt1mb4iCQonTgVOBWQGcVJ8d JW4AnR1DKOrDCf8O5/+B6uGAvDVeFRJ4 =SloR -----END PGP SIGNATURE----- --+Z7/5fzWRHDJ0o7Q--
