最近给Ubuntu添加了一块硬盘，下面是具体的步骤

买的云服务器IDC给了一块10GB的数据盘，因为系统盘不大，就要把数据盘用上了

但是Linux下数据盘并没有挂载，Linux的磁盘系统也不同于windows，需要挂载使用

1、新建分区并格式化

使用

fdisk -l

查看当前的硬盘，可以看到有sda、sdb两块盘，第一块作为系统盘已经分区，sdb就是我们要挂载的数据盘

首先进行分区

fdisk /dev/sdb

进入磁盘sdb（如果你是磁盘sdc就相应的替换为sdc）相当于选中这个硬盘的意思

首先输入m看一下帮助

比较简单，应该很容易看懂，暂时把几个常用的写上了意思

Command (m for help): p                                        ##显示磁盘信息
Disk /dev/sdb: 10 GiB, 10737418240 bytes, 20971520 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: dos
Disk identifier: 0xb5106536
Command (m for help): n                                        ##新建分区
Partition type
p   primary (0 primary, 0 extended, 4 free)
e   extended (container for logical partitions)
Select (default p): p                                          ##新建逻辑分区
Partition number (1-4, default 1):
First sector (2048-20971519, default 2048):
Last sector, +sectors or +size{K,M,G,T,P} (2048-20971519, default 20971519):
##直接留空，我只想把所有的空间分一个分区
Created a new partition 1 of type &##39;Linux&##39; and of size 10 GiB.
Command (m for help): w                                        ##保存退出
The partition table has been altered.
Calling ioctl() to re-read partition table.
Syncing disks.

再次使用fdisk -l已经可以看到sdb有一个分区sdb1了

同Windows一样，磁盘需要格式化后才能使用

用

mkntfs /dev/sdb1

来格式化为NTFS格式，其他格式可以自行百度

出现

Cluster size has been automatically set to 4096 bytes.
Initializing device with zeroes: 100% - Done.
Creating NTFS volume structures.
mkntfs completed successfully. Have a nice day.

即为格式化完成

2、挂载磁盘

临时挂载可以使用mount命令，但是重启后需要重新挂载

用法为

mount 分区 目录

比如我需要使用

mount /dev/sdb1 /data

挂载

（当然前提是存在目录/data）

编辑

/etc/fstab

来永久挂载磁盘

## /etc/fstab: static file system information.
## 
## Use &##39;blkid&##39; to print the universally unique identifier for a
## device; this may be used with UUID= as a more robust way to name devices
## that works even if disks are added and removed. See fstab(5).
##
## <file system> <mount point>   <type>  <options>       <dump>  <pass>
## / was on /dev/sda1 during installation
UUID=22e202f3-ae04-4995-b214-de7f192f33c4 /               ext4    errors=remount-ro 0       1
## swap was on /dev/sda5 during installation
UUID=472580b3-a87b-4fe2-8bda-59b59d087ec6 none            swap    sw              0       0
/dev/fd0        /media/floppy0  auto    rw,user,noauto,exec,utf8 0       0
/dev/sdb1       /data   ntfs    defaults        0       0
磁盘           挂载目录 磁盘格式

需要注意的是，中间的空不需要打空格，用TAB制表符更方便

root@rootadmin:/data## mkdir blog root@rootadmin:/data## dir blog root@rootadmin:/data## reboot Connection closing...Socket close.

重启了一下，挂载确实成功了
