Linux增加磁碟
使用Fdisk工具進行分割槽;
格式化;
掛載;
[@more@]--首先看看有哪些磁碟
[root@localhost ~]# fdisk -l
--要處理的是sdj,使用fdisk分割槽
[root@localhost ~]# fdisk /dev/sdj
The number of cylinders for this disk is set to 13054.
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): m
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
Command action
e extended
p primary partition (1-4)
p
Partition number (1-4): 1
First cylinder (1-13054, default 1): 1
Last cylinder or +size or +sizeM or +sizeK (1-13054, default 13054):
Using default value 13054
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
Command (m for help):q
--這之間使用了n建立分割槽,p是主分割槽,最重要的是w,寫入磁碟,不寫的話,前面工作白費
--下面是使用ext3格式格式化sdj1
[root@localhost ~]# mkfs.ext3 /dev/sdj1
mke2fs 1.39 (29-May-2006)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
13107200 inodes, 26214055 blocks
1310702 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=4294967296
800 block groups
32768 blocks per group, 32768 fragments per group
16384 inodes per group
Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,
4096000, 7962624, 11239424, 20480000, 23887872
Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done
This filesystem will be automatically checked every 34 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
--格式化完畢,檢視一下列表
[root@localhost ~]#fdisk -l
Disk /dev/sdj: 107.3 GB, 107374182400 bytes
255 heads, 63 sectors/track, 13054 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sdj1 1 13054 104856223+ 83 Linux
--終於有磁碟了
--建立掛載點
[root@localhost ~]# mkdir /hdsdj
--掛載磁碟上去
[root@localhost ~]# mount /dev/sdj1 /hdsdj
--驗證下效果
[root@localhost ~]# cd /
[root@localhost /]# ls
bin boot dev etc hdsdj hdsdn hdsdo home lib lib64 lost+found media misc mnt opt proc root sbin selinux srv sys tmp usr var
--重啟後就消失,寫入磁碟記錄
[root@localhost /]# vi /etc/fstab
--重啟驗證一下
[root@localhost /]#reboot
