Centos 7.0挂载硬盘
Centos 7.0挂载硬盘
1.输入fdisk -l命令看当前磁盘信息
fdisk -l
查看硬盘信息
Disk /dev/vda: 42.9 GB, 42949672960 bytes, 83886080 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0x000d2717

Disk /dev/vdb: 214.7 GB, 214748364800 bytes, 419430400 sectors

Sector size (logical/physical): 512 bytes / 512 bytes

2.进入需要挂载的分区
fdisk /dev/vdb1
Welcome to fdisk (util-linux 2.23.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
Device does not contain a recognized partition table
Building a new DOS disklabel with disk identifier 0x4873179f.
Command (m for help): n
3.按n进行分区
Partition type:
p primary (0 primary, 0 extended, 4 free) //主分区
e extended //扩展分区
4.选择默认的主分区
Select (default p): p
5.选择安装到第几个主分区,这里我选择第一个分区
Partition number (1-4, default 1): 1
6.选择该分区的起始磁盘数(默认)，选择默认值就好
First sector (2048-419430399, default 2048):
7.定义该分区的大小，如果按默认（按回车）即是使用全部可用存储额
Last sector, +sectors or +size{K,M,G} (2048-419430399, default 419430399):
Using default value 419430399
8.输入w 写入分区,成功后会出现如下提示
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
9.格式化分区
mkfs -t ext3 -c /dev/vdb1
[root@izbp10ndtnrkwpf2c01z5cz ~]# mkfs -t ext3 -c /dev/vdb1

10 .如果想每次系统重启都能自动挂载该分区可修改/etc/fstab文件
echo “/dev/vdb1 /home ext3 defaults 1 2” >> /etc/fstab
11. 挂载分区到home目录
mount /dev/vdb1 /home
12. 查看是否挂载成功
这里显示已经挂载了一个187G的硬盘
df -lh
