把磁盘sdb的容量用了创建一个分区 /dev/sdb1 ,把这个分区挂载到/mnt 

有了硬盘,分区,格式化创建文件系统,挂载

第一步:创建分区

fdisk -cu /dev/sdb


Command (m for help): p


Disk /dev/sdb: 106 MB, 106954752 bytes

64 heads, 32 sectors/track, 102 cylinders, total 208896 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 identifier: 0x0c7ada8f


   Device Boot      Start         End      Blocks   Id  System


Command (m for help): n

Command action

   e   extended

   p   primary partition (1-4)

p

Partition number (1-4): 1

First sector (2048-208895, default 2048): 

Using default value 2048

Last sector, +sectors or +size{K,M,G} (2048-208895, default 208895): 

Using default value 208895


Command (m for help): p


Disk /dev/sdb: 106 MB, 106954752 bytes

64 heads, 32 sectors/track, 102 cylinders, total 208896 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 identifier: 0x0c7ada8f


   Device Boot      Start         End      Blocks   Id  System

/dev/sdb1            2048      208895      103424   83  Linux

Command (m for help): w

The partition table has been altered!


Calling ioctl() to re-read partition table.

Syncing disks.

第二步:通知系统 /dev/sdb磁盘的分区表修改了  变化了

partprobe /dev/sdb

第三步:格式化创建文件系统 

mkfs.ext4 /dev/sdb1

mkfs.ext4 /dev/sdb1


mke2fs 1.41.12 (17-May-2010)

Filesystem label=

OS type: Linux

Block size=1024 (log=0)

Fragment size=1024 (log=0)

Stride=0 blocks, Stripe width=0 blocks

25896 inodes, 103424 blocks

5171 blocks (5.00%) reserved for the super user

First data block=1

Maximum filesystem blocks=67371008

13 block groups

8192 blocks per group, 8192 fragments per group

1992 inodes per group

Superblock backups stored on blocks: 

8193, 24577, 40961, 57345, 73729


Writing inode tables: done                            

Creating journal (4096 blocks): done

Writing superblocks and filesystem accounting information: done


This filesystem will be automatically checked every 21 mounts or

180 days, whichever comes first.  Use tune2fs -c or -i to override.

第四步让系统不对我们新创建的分区 进行磁盘检查

tune2fs -c 0 -i 0  /dev/sdb1 

tune2fs 1.41.12 (17-May-2010)

Setting maximal mount count to -1

Setting interval between checks to 0 seconds

第五步:挂载 与检查

mount /dev/sdb1 /mnt/

[root@oldboyedu-39-nb ~]# df -h

Filesystem      Size  Used Avail Use% Mounted on

/dev/sda3       8.8G  1.7G  6.8G  20% /

tmpfs           931M     0  931M   0% /dev/shm

/dev/sda1       190M   40M  141M  22% /boot

/dev/sdb1        94M  1.6M   88M   2% /mnt

第六步:需要永久挂载  开机自动挂载

----挂载命令放入到  /etc/rc.local 文件中

/bin/mount /dev/sdb1 /mnt/
