IBM服務(wù)器，Linux系統(tǒng)，三塊硬盤做Raid5，今天終于成功加上了塊硬盤！
1、用Raid驅(qū)動(dòng)盤（是不是這么叫？呵呵）引導(dǎo)，將新加的盤做Raid0(因?yàn)橹患恿艘粔K盤)
2、通過fdisk分區(qū)
3、通過mkfs.ext3格式化新的分區(qū)，完成
第一步很簡單
第二步，分區(qū)
1、通過fdisk -l查看未分區(qū)硬盤
Disk /dev/sda: 72.8 GB, 72802631680 bytes
254 heads, 63 sectors/track, 8885 cylinders
Units = cylinders of 16002 * 512 = 8193024 bytes
Device Boot Start End Blocks Id System
/dev/sda1 * 1 13 103981+ 83 Linux
/dev/sda2 14 8656 69152643 83 Linux
/dev/sda3 8657 8885 1832229 82 Linux swap
Disk /dev/sdb: 36.4 GB, 36401315840 bytes
254 heads, 63 sectors/track, 4442 cylinders
Units = cylinders of 16002 * 512 = 8193024 bytes
Device Boot Start End Blocks Id System
這兒可以看到，/dev/sdb尚未分區(qū)
2、通過fdisk /dev/sdb對/dev/sdb進(jìn)行分區(qū)
[root@ckkhserver root]# fdisk /dev/sdb
The number of cylinders for this disk is set to 4442.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Command (m for help):
鍵入m查看幫助
Command action
a toggle a bootable flag
b edit bsd disklabel
c toggle the dos compatibility flag
d delete a partition
l list known partition types
m print this menu
n add a new partition
o create a new empty DOS partition table
p print the partition table
q quit without saving changes
s create a new empty Sun disklabel
t change a partition's system id
u change display/entry units
v verify the partition table
w write table to disk and exit
x extra functionality (experts only)
選n add a new partition，創(chuàng)建一分區(qū)
Command action
e extended
p primary partition (1-4)
我不知道這是什么意思，但嘗試后知道，應(yīng)該選p primary partition (1-4)
然后根據(jù)情況鍵入數(shù)字，比如1
再根據(jù)提示選擇分區(qū)的類型，L查看知道有這么一個(gè)類型，83 Linux
那就選這個(gè)類型，輸入83，然后保存退出，分區(qū)就完成了
第三步，格式化
這兒，格式化成ext3格式，命令為mkfs.ext3 /dev/hdb1
為了讓硬盤在系統(tǒng)啟動(dòng)時(shí)自動(dòng)掛載，用vi編輯/etc/fstab文件，加入如下內(nèi)容（比如掛載到/mnt/hd目錄）
/dev/dhb1 /mnt/hd reiserfs defaults 1 1
