脚本宝典收集整理的这篇文章主要介绍了CentOS下添加新硬盘并分区格式化的详细步骤,脚本宝典觉得挺不错的,现在分享给大家,也给大家做个参考。
下面看我操作的步骤:
@H_
360_1@1.先用
Fdisk -l 来查看当前状态下磁盘情况
&nbs
p;[root@linux1 ~]
# f
disk -l
Disk /dev/hda: 5368 MB, 5368709120 bytes
255 heads, 63 sectors/track, 652 cylinders
Un
ITs = cylinders of 16065 *
512 = 8225280 bytes
Device Boot Start End Blocks Id
System
/dev/hda1 * 1 13 104391 83 Linux
/dev/hda2 14 652 5132767 8e Linux
LVMDisk /dev/hdb: 2147 MB, 2147483648 bytes
16 heads, 63 sectors/track, 4161 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes
Disk /dev/hdb doesn't cont
ain a valid partition table
上面
红色标识行可以看出,我添加了
一块新硬盘/dev/hdb,大小为2G,未分区格式化状态。
2.用Fdisk /dev/hdb来进行分区操作。
[root@linux1 ~]# fdisk /dev/hdb
Device contains n
either 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 t
hat, of course, the p
revious
content won't be recoverable.
The number of cylinders for this disk is set to 4161.
There is nothing wrong with that, but this is l
arger 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)
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
Command (m for help): n //输入N表示新建一个分区
Command action
e extended
p
Primary partition (1-4)
p //p 表示建立一个原始分区
Partition number (1-4): 1 //1 表示此分区编号为1.
First cylinder (1-4161, default 1): 1 //1表示使用默认起始柱面号.如果要分多个区的话,先盘算好要多大,再输入数字
Last cylinder or size or sizeM or sizeK (1-4161, default 4161): // 输入: 回车 表示使用默认结束柱面号.即此分区使用整个硬盘空间
Using default value 4161
Command (m for help): w //保存分区
The partition table has been alte
red!
Calling ioctl() to re-read partition table.
Syncing disks.
3.再次查看当前分区状态:
[root@linux1 ~]# fdisk -l
Disk /dev/hda: 5368 MB, 5368709120 bytes
255 heads, 63 sectors/track, 652 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hda1 * 1 13 104391 83 Linux
/dev/hda2 14 652 5132767 8e Linux LVM
Disk /dev/hdb: 2147 MB, 2147483648 bytes
16 heads, 63 sectors/track, 4161 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes
Device Boot Start End Blocks Id System
/dev/hdb1 1 4161 2097112 83 Linux
可以看出,已经出来了一个/dev/hdb1的新分区。下一步将其格式化,再使用
4.用Mkfs.ext3格式化新分区
[root@linux1 ~]# mkfs.ext3 /dev/hdb1
mke2fs 1.39 (29-May-2006)
Filesystem label=
OS ty
PE: Linux
Block size=4096 (
LOG=2)
Fragment size=4096 (log=2)
262144 inodes, 524278 blocks
26213 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=536870912
16 block groups
32768 blocks per group, 32768 fragments per group
16384 inodes per group
Superblock backups
Stored on blocks:
32768, 98
304, 163840, 229376, 294912
Writing inode tables: done
Writing superblocks and filesystem accounting information: done
This filesystem will be automat
ically checked every 32
mounts or
180 days,
whichever comes first. Use tune2fs -c or
-i to
override.
5.挂载使用。
[root@linux1 ~]# mkdir /mnt/hdb1 //新建一个挂载点。
[root@linux1 ~]# mount /dev/hdb1 /mnt/hdb1 //挂载。
[root@linux1 ~]#
DF -h
文件系统 容量 已用 可用 已用% 挂载点
/dev/mapper/VolGroup00-LogVol00
4.3G 3.6G 487M 89% /
/dev/hda1 99M 12M 82M 13% /boot
@R_37_
1262@ 125M 0 125M 0% /dev/shm
/dev/hdb1 2.0G 3.0M 1.9G 1% /mnt/hdb1
6 .开机自动挂载
三.设置新硬盘开机自动挂载
在vi /etc/fstab中添加新硬盘的挂载信息.添加下面一行:
/dev/hdb1 /mnt/hdb1 ext3
defaults 1 2(如果还有一个分区就是1 3,以此类推)
这样,每次开机后,系统会自动将/dev/hdb1挂载到/mnt/hdb1
