阿里云ECS服务器(linux)挂载硬盘  
1.查看系统挂载  
\[root@iZ234wzhfriZ ~\]\# df -h  
Filesystem      Size  Used Avail Use% Mounted on  
/dev/vda1        40G  2.3G   36G   7% /  
tmpfs           3.9G     0  3.9G   0% /dev/shm  
2.查看磁盘列表(vdb还没有进行分区)  
\[root@iZ234wzhfriZ ~\]\# fdisk -l  
Disk /dev/vda: 42.9 GB, 42949672960 bytes  
255 heads, 63 sectors/track, 5221 cylinders  
Units = cylinders of 16065 \* 512 = 8225280 bytes  
Sector size (logical/physical): 512 bytes / 512 bytes  
I/O size (minimum/optimal): 512 bytes / 512 bytes  
Disk identifier: 0x00078f9c  
  
   Device Boot      Start         End      Blocks   Id  System  
/dev/vda1   \*           1        5222    41940992   83  Linux  
Disk /dev/vdb: 107.4 GB, 107374182400 bytes  
16 heads, 63 sectors/track, 208050 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  
  
3.分区：  
fdisk /dev/vdb   
\[root@iZ234wzhfriZ ~\]\# fdisk -l  
Disk /dev/vda: 42.9 GB, 42949672960 bytes  
255 heads, 63 sectors/track, 5221 cylinders  
Units = cylinders of 16065 \* 512 = 8225280 bytes  
Sector size (logical/physical): 512 bytes / 512 bytes  
I/O size (minimum/optimal): 512 bytes / 512 bytes  
Disk identifier: 0x00078f9c  
  
   Device Boot      Start         End      Blocks   Id  System  
/dev/vda1   \*           1        5222    41940992   83  Linux  
  
Disk /dev/vdb: 107.4 GB, 107374182400 bytes  
16 heads, 63 sectors/track, 208050 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: 0x1ef51bc1  
   Device Boot      Start         End      Blocks   Id  System  
/dev/vdb1               1      208050   104857168+  83  Linux  
  
4.格式分区/dev/vdb1：  
mkfs.ext4 /dev/vdb1  
\[root@iZ234wzhfriZ ~\]\# mkfs.ext4 /dev/vdb1  
mke2fs 1.41.12 (17-May-2010)  
Filesystem label=  
OS type: Linux  
Block size=4096 (log=2)  
Fragment size=4096 (log=2)  
Stride=0 blocks, Stripe width=0 blocks  
6553600 inodes, 26214292 blocks  
1310714 blocks (5.00%) reserved for the super user  
First data block=0  
Maximum filesystem blocks=4294967296

        4096000, 7962624, 11239424, 20480000, 23887872  
  
Writing inode tables: done                              
Creating journal (32768 blocks): done  
Writing superblocks and filesystem accounting information: done  
This filesystem will be automatically checked every 31 mounts or  
180 days, whichever comes first.  Use tune2fs -c or -i to override.  
  
5.挂载：  
创建挂载目录  
\[root@iZ234wzhfriZ /\]\# mkdir data  
mount /dev/vdb1 /data  
\[root@iZ234wzhfriZ /\]\# df -h  
Filesystem      Size  Used Avail Use% Mounted on  
/dev/vda1        40G  2.3G   36G   7% /  
tmpfs           3.9G     0  3.9G   0% /dev/shm  
/dev/vdb1        99G  188M   94G   1% /data  
  
6.把挂载配置/etc/fstab中重启会自动挂载
