Have 3 drives: 1.5 TB WD15EARS, 1 TB Fantom Green (eSATA), 2 TB WD20EARS.
\nFirst, did a:
\n
\nserver# gpart add -b 2048 -s 2929865452 -t freebsd-zfs -l WD15EARS ada0
\nada0p1 added
\nserver# gpart add -b 2048 -s 1953113452 -t freebsd-zfs -l FANTOM1TB ada1
\nada1p1 added
\nserver# gpart add -b 2048 -s 3906617452 -t freebsd-zfs -l WD20EARS ada2
\nada2p1 added
\n<\/code>
\nNow, I have:
\n
\nserver# gpart show ada0
\n=> 34 2930277101 ada0 GPT (1.4T)
\n 34 2014 - free - (1.0M)
\n 2048 2929865452 1 freebsd-zfs (1.4T)
\n 2929867500 409635 - free - (200M)<\/p>\n

server# gpart show ada1
\n=> 34 1953525101 ada1 GPT (932G)
\n 34 2014 - free - (1.0M)
\n 2048 1953113452 1 freebsd-zfs (931G)
\n 1953115500 409635 - free - (200M)<\/p>\n

server# gpart show ada2
\n=> 34 3907029101 ada2 GPT (1.8T)
\n 34 2014 - free - (1.0M)
\n 2048 3906617452 1 freebsd-zfs (1.8T)
\n 3906619500 409635 - free - (200M)
\n<\/code>
\nYou’ll note that I’m leaving 200M free in case I replace the drive with a slightly smaller drive.
\nNext step: set up ZFS pools.<\/p>\n
