Linux添加新硬盘及分区，格式化，挂载

1、查看分区信息：

[root@localhost /]# fdisk -l

Disk /dev/vdb: 209.7 GB, 209715200000 bytes
16 heads, 63 sectors/track, 406349 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

2、硬盘分区：

[root@localhost /]# fdisk /dev/vdb

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 (1-406349, default 1):
Using default value 1
Last cylinder, +cylinders or +size{K,M,G} (1-406349, default 406349):
Using default value 406349

3、格式化硬盘：

[root@localhost /]# mkfs -t ext4 /dev/vdb1

4、挂载硬盘分区：

[root@localhost /]# mount /dev/vdb1 /home

4.1、卸载硬盘分区：

[root@localhost /]# umount /home

5、添加挂载命令到系统启动项：

[root@localhost ]# vim /etc/fstab
/dev/vdb1               /home                   ext4    defaults        0 0

5.1、以UUID号挂载到系统启动项：

[root@localhost ]# blkid
/dev/vdb1: UUID="480cef7b-6bb3-4481-b97d-2adb552b35c6" TYPE="ext4" 

[root@localhost ]# vim /etc/fstab
UUID=480cef7b-6bb3-4481-b97d-2adb552b35c6       /home            ext4    defaults        0 0

[THE END]
