18.2. RAID0 – 分散連結(striping)
OS：FreeBSD 10.3
HDD：
20G*1：FreeBSDSystem(/dev/da0)
20G *3 ：RAID (/dev/da1,da2,da3)
1. 載入 geom_stripe.ko Kernel Module
# kldload geom_stripe.ko
或
# gstripe load
2. 查看系統目前載入之核心模組
# kldstat
Id Refs Address Size Name
1 6 0xffffffff80200000 17bc680 kernel
2 1 0xffffffff81a11000 2ba8 uhid.ko
3 1 0xffffffff81a14000 46d7 geom_stripe.ko[@more@]3. 產生 RAID0 Gvinum Plex
# gstripe label -v myraid0 /dev/da1 /dev/da2 /dev/da3
Metadata value stored on /dev/da1.
Metadata value stored on /dev/da2.
Metadata value stored on /dev/da3.
Done.
4. 修改串連後的 HDD 為 GVinum volume
# bsdlabel -wB /dev/stripe/myraid0
5. 初始化 Gvinum 分割區
# newfs -U /dev/stripe/myraid0a
/dev/stripe/myraid0a: 61439.8MB (125828720 sectors) block size 32768, fragment size 4096
using 99 cylinder groups of 626.09MB, 20035 blks, 80256 inodes.

6. 掛載 Gvinum 分割區
# mount /dev/stripe/myraid0a /mnt
7. 查看磁碟機狀況
# df -h
Filesystem Size Used Avail Capacity Mounted on
/dev/da0p2 18G 2.8G 14G 17% /
devfs 1.0K 1.0K 0B 100% /dev
/dev/stripe/myraid0a 58G 8.0K 53G 0% /mnt
8. 修改 /etc/fstab
# vim /etc/fstab
加入下面一行
/dev/stripe/myraid0a /mnt ufs rw 2 2
9. 開機便啟動 GVinum 服務
修改 /boot/loader.conf 設定檔
# vim /boot/loader.conf
加入下面一行
geom_stripe_load=”YES”
10. 查看所建立 Software RAID 狀態
# gstripe status
