Linux 下挂载硬盘方法

    刚安装的新的硬盘，由于没有格式化，所以在linux下无法识别这个硬盘，所以要先挂载这个硬盘。

1、添加屏硬盘，查看硬盘状况

      利用fdisk -l命令可以看出，多了个/dev/sdb大小为1T的盘。

2、用fdisk对/dev/sdb进行分区

root@pb25-desktop:~# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x4e4b62cd.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.

Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

The device presents a logical sector size that is smaller than
the physical sector size. Aligning to a physical sector (or optimal
I/O) size boundary is recommended, or performance may be impacted.

Command (m for help): n
Partition type:
   p   primary (0 primary, 0 extended, 4 free)
   e   extended
Select (default p): p
Partition number (1-4, default 1): 1
First sector (2048-1953525167, default 2048):
Using default value 2048
Last sector, +sectors or +size{K,M,G} (2048-1953525167, default 1953525167):
Using default value 1953525167


Command (m for help): w
The partition table has been altered!

Calling ioctl() to re-read partition table.
Syncing disks.

      当Command (m for help):时选择n，Select (default p):时选择p，Partition number (1-4, default 1):时选择1，然后再次出现Command (m for help):时选择w。
然后再次利用fdisk -l命令查看分区情况，多出来了一个dev/sdb1的区，这个1就是在Partitionnumber (1-4, default 1)指定的1，如果选择2就为dev/sdb2。

     如果创建完之后，/proc/partitions 查看不到对应的分区，使用parprobe 命令刷新一下就可以了：

3、格式化/dev/sdb1分区

     格式化分区利用mkfs -t ext3 /dev/sdb1进行格式化/dev/sdb1分区；

4. 创建目录 并将 /dev/sdb1 挂在到该目录下

5、查看是否挂载成功

    利用df -k命令进行查看

6. 设置开机自动挂载

root@pb25-desktop:/# vim /etc/fstab
  1 # /etc/fstab: static file system information.
  2 #
  3 # Use 'blkid' to print the universally unique identifier for a
  4 # device; this may be used with UUID= as a more robust way to name devices
  5 # that works even if disks are added and removed. See fstab(5).
  6 #
  7 # <file system> <mount point>   <type>  <options>       <dump>  <pass>
  8 proc            /proc           proc    nodev,noexec,nosuid 0       0
  9 # / was on /dev/sda1 during installation
10 UUID=8afe0489-190e-47ce-a72e-76e53dbb5b52 /               ext4    errors=remount-ro 0       1
11 # /home was on /dev/sda5 during installation
12 UUID=3c6604bd-c071-444f-b726-d4fc9bc9e101 /home           ext4    defaults        0       2
13 # swap was on /dev/sda2 during installation
14 UUID=3f791267-c2bd-46c4-b7df-fb9cdf5c4eeb none            swap    sw              0       0

  然后加上下面内容：/dev/sdb1      /disk01         ext3   defaults       0       0

1 # /etc/fstab: static file system information.
  2 #
  3 # Use 'blkid' to print the universally unique identifier for a
  4 # device; this may be used with UUID= as a more robust way to name devices
  5 # that works even if disks are added and removed. See fstab(5).
  6 #
  7 # <file system> <mount point>   <type>  <options>       <dump>  <pass>
  8 proc            /proc           proc    nodev,noexec,nosuid 0       0
  9 # / was on /dev/sda1 during installation
10 UUID=8afe0489-190e-47ce-a72e-76e53dbb5b52 /               ext4    errors=remount-ro 0       1
11 # /home was on /dev/sda5 during installation
12 UUID=3c6604bd-c071-444f-b726-d4fc9bc9e101 /home           ext4    defaults        0       2
13 # swap was on /dev/sda2 during installation
14 UUID=3f791267-c2bd-46c4-b7df-fb9cdf5c4eeb none            swap    sw              0       0
15 /dev/sdb1       /disk01         ext3    defaults        0       0

   这样就可以将硬盘挂载上了。
