公司內(nèi)網(wǎng)的服務(wù)器硬盤空間不足，將新買來的150G硬盤掛載并設(shè)置成samba的共享目錄，關(guān)于samba請(qǐng)參考此文章hi.baidu/linglongwunv/blog/item/56ec2beb6f0fcfdad439c942.html，下面介紹怎樣將一塊新硬盤分區(qū)、格式化、掛載到系統(tǒng)，如適合你請(qǐng)繼續(xù)閱讀。服務(wù)器上已經(jīng)有兩塊硬盤，所以硬盤為sdc，后面就不做說明了，至于不知道sdc怎么回事的人，先去問問百度大哥再回來接著看。
1、# fdisk -l 查看當(dāng)前磁盤信息，就會(huì)發(fā)現(xiàn)最下面顯示新加入的硬盤不是有效分區(qū)，如下：
Disk /dev/sdc: 1500.3 GB, 1500301910016 bytes
255 heads, 63 ctors/track, 182401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk /dev/sdc doesn't contain a valid partition table
2、# fdisk /dev/sdc 對(duì)新硬盤分區(qū)，并根據(jù)提示進(jìn)一步操作
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of cour, the previous
content won't be recoverable.
The number of cylinders for this disk is t to 182401.
There is nothing wrong with that, but this is larger than 1024,
and could in certain tups cau 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)
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
Command (m for help): h 輸入h可查看幫助命令
h: unknown command
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)
Command (m for help): n 輸入n進(jìn)行分區(qū)
Command action
e extended
p primary partition (1-4)
p 輸入p為主分區(qū)，e為邏輯分區(qū)
Partition number (1-4): 1 由于是新盤我們輸入1來分第一個(gè)主分區(qū)，共可以分4個(gè)主分區(qū)
First cylinder (1-182401, default 1): 選擇該分區(qū)的起始磁盤數(shù)，如無特殊需求強(qiáng)烈建議選擇默認(rèn)，也就是1來分區(qū)（直接按回車）
Using default value 1
Last cylinder or +size or +sizeM or +sizeK (1-182401, default 182401): 定義該分區(qū)的大小，如果按默認(rèn)（按回車）即是使用全部可用存儲(chǔ)額，如分一個(gè)1G的空間，輸入+1024m
Using default value 182401
Command (m for help): w 寫入分區(qū)
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
3、# fdisk -l 可以找到我們剛才分的一個(gè)分區(qū)，內(nèi)容如下：
Disk /dev/sdc: 1500.3 GB, 1500301910016 bytes
255 heads, 63 ctors/track, 182401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sdc1 1 182401 1465136001 83 Linux
4、# mkfs -t ext3 -c /dev/sdc1 對(duì)分區(qū)使用ext3格式化，如多個(gè)分區(qū)sdc2等以此類推，因?yàn)樾掠脖P加了-c參數(shù)要先檢測(cè)磁盤壞道，此過程萬分漫長(zhǎng)（150G），等待。。。

5、# mkdir /var/samba 新建掛載目錄
6、# mount /dev/sdc1 /var/samba 掛載新硬盤
7、# df -hl 查看分區(qū)大小是否和我們預(yù)定的一樣：
文件系統(tǒng) 容量 已用 可用 已用% 掛載點(diǎn)
/dev/sda7 9.5G 3.2G 5.9G 35% /
/dev/sda6 9.5G 151M 8.9G 2% /tmp
/dev/sda5 19G 3.6G 15G 20% /usr
/dev/sda3 19G 719M 18G 4% /home
/dev/sda2 230G 23G 196G 11% /var
/
dev/sda1 99M 25M 69M 27% /boot
/dev/sdb1 233G 156G 78G 67% /var/samba2
tmpfs 1008M 0 1008M 0% /dev/shm
/dev/sdc1 1.4T 198M 1.3T 1% /var/samba 此行為新硬盤
8、# vi /etc/fstab 設(shè)置系統(tǒng)自動(dòng)掛載硬盤，加入一行：
/dev/sdc1 /var/samba2 ext3 defaults 0 0
9、重啟服務(wù)器，用步驟7檢查一下，一切正常掛載完成，祝好運(yùn)~
