一、創建新分區
首先查看已經有的分區:
root@ubuntu:/# fdisk -l
Disk /dev/sda: 32.2 GB, 32212254720 bytes
255 heads, 63 sectors/track, 3916 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000e11ac
Device Boot Start End Blocks Id System
/dev/sda1 * 1 1871 15021056 83 Linux
/dev/sda2 1871 1958 704513 5 Extended
/dev/sda5 1871 1958 704512 82 Linux swap / Solaris
root@ubuntu:/#
從上面的信息看出/dev/sda1、/dev/sda2兩個主分區,那么我們可以創建一個/dev/sda3
root@ubuntu:/# fdisk /dev/sda
WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
switch off the mode (command 'c') and change display units to
sectors (command 'u').
Command (m for help):
m for help就看的出,輸入 m 為幫助;
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)
Command (m for help):
從上面信息知道,n 為添加分區,即新建分區;w 為保存。
Command (m for help): n
Command action
l logical (5 or over)
p primary partition (1-4)
創建邏輯分區還是主分區,這里輸入 p 創建主分區。
如果出現:
Selected partition 4
No free sectors available
表示沒有空閑硬盤,這時你得手動在虛擬機上添加。
接着按默認數據輸入,最后記得輸入 w 保存。q為退出。
二、格式化新建分區並設置掛載點
格式化:
root@ubuntu:/# mkfs.ext4 /dev/sda3
創建掛載點:
root@ubuntu:/# mount -t ext4 /dev/sda3 /home/work
把新建的分區掛載到/home/work目錄,/home/work目錄大小就為自己先添加的硬盤大小。
這時你就可以查看到home/work里面有個lost+found目錄。
三、讓系統開機自動掛載
只要在/etc/fstab中添加一行,做過根文件系統的應該知道:
/dev/sda3 /home/work ext4 defaults 1 0
重啟下就可以見效了。
查看使用情況:
root@ubuntu:/# df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda1 14784996 5147264 8886680 37% /
none 248640 208 248432 1% /dev
none 254244 248 253996 1% /dev/shm
none 254244 384 253860 1% /var/run
none 254244 0 254244 0% /var/lock
/dev/sda3 15480852 8684096 6010376 60% /home/work
root@ubuntu:/#
當然在/home/work目錄,我已經添加了很多東西。
