Hum, is/was this documented somewhere? I just set up two RAID-5's on -STABLE, and I have done this every time I did a RAID setup with vinum. I'd hate it if I'd have to migrate 300GB of data because I didn't reserve 16 sectors at the start of a disk :( --Stijn --=20 If today is the first day of the rest of your life, what the hell was yesterday? --mSxgbZZZvrAyzONB Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (FreeBSD) iD8DBQFA3XQTY3r/tLQmfWcRAjgPAKCN/CbZuqhYOKD4kG1BodVDHlUPxwCdHclz iFkSXGUsB3wNoMz672tB73Q= =3HxX -----END PGP SIGNATURE----- --mSxgbZZZvrAyzONB--
