Menambah disk baru di OpenBSD
Disk baru: IDE SAMSUNG SV0411N 40GB
1. check dmesg
#dmesg |grep wd
wd0 at pciide0 channel 0 drive 0: < st310014a >
wd0: 16-sector PIO, LBA, 9767MB, 20003537 sectors
wd1 at pciide0 channel 0 drive 1: < samsung >
wd1: 16-sector PIO, LBA48, 38204MB, 78242976 sectors
wd0(pciide0:0:0): using PIO mode 4, Ultra-DMA mode 5
wd1(pciide0:0:1): using PIO mode 4, Ultra-DMA mode 5
wd0 : hdd system dimana OpenBSD diinstall
wd1 : hdd baru yang akan ditambahkan ke system
2. ok..menuju ke partisi disk
#fdisk -i wd1
akan muncul pertanyaan :
Do you wish to write new MBR and partition table? [n]
ketik : y enter
3. Buat table partisi
#disklabel -E wd1
kita akan dibawa ke simple editor jika perintah disklabel ditambahkan option -E
> p g
device: /dev/rwd1c
type: ESDI
disk: ESDI/IDE disk
label: SAMSUNG SV0411N
bytes/sector: 512
sectors/track: 63
tracks/cylinder: 16
sectors/cylinder: 1008
cylinders: 16383
total bytes: 37.3G
free bytes: 0.0G
rpm: 3600
16 partitions:
# size offset fstype [fsize bsize cpg]
a: 37.3G 0.0G 4.2BSD 2048 16384 16
c: 37.3G 0.0G unused 0 0
Keterangan perintah dalam simple editor :
p [spasi] [satuan] : menampilkan tabel partisi yang telah dibuat
[satuan m:megabytes g:gigabyte k:kilobyte b:byte]
a [spasi] [label partisi] : menambahkan table partisi
[label partisi] : a - p
d [spasi] [label partisi] : menghapus table partisi
e : edit parameter disk
q : keluar sekaligus menyimpan table partisi
Example :
menambahkan table satu table partisi dengan besar 30GB :
> a a
offset: [63]
size: [78236487] 30g
Rounding to cylinder: 62915265
FS type: [4.2BSD]
> q
Write new label?: [y]
4. Format table partisi :
#newfs wd1a
memformat table partisi a disk wd1 [harddisk baru]
/dev/rwd1a: 30720.3MB in 62915264 sectors of 512 bytes
152 cylinder groups of 202.47MB, 12958 blocks, 25984 inodes each

di atas adalah proses format wd1a
5. Mounting partisi baru
Buat direktori dimana partisi baru akan dimount
#mkdir /cache/
#mount /dev/wd1a /cache
Terakhir masukkan ke /etc/fstab :
#nano /etc/fstab
/dev/wd1a /cache ffs rw,nodev,nosuid 1 1
#reboot
Check kembali apakah partisi baru sudah otomatis dimounting ke /cache
#mount
/dev/wd1a on /cache type ffs (local, nodev, nosuid)
Finish sampe disini dulu, kalau ada pertanyaan & masukan lain silakan kirim comment!
