刚买的阿里云机器，是不会自动挂载高效云盘的，需要手工处理.

1.查看云盘

[root@xxx ~]# fdisk -l

Disk /dev/vda: 53.7 GB, 53687091200 bytes, 104857600 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 label type: dos
Disk identifier: 0x000d2717

   Device Boot      Start         End      Blocks   Id  System
/dev/vda1   *        2048   104855551    52426752   83  Linux

Disk /dev/vdb: 536.9 GB, 536870912000 bytes, 1048576000 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

[root@xxx ~]#

可以看到系统已经识别为/dev/vdb

2.格式化

[root@xxx ~]# mkfs.ext4 /dev/vdb
mke2fs 1.42.9 (28-Dec-2013)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
Stride=0 blocks, Stripe width=0 blocks
32768000 inodes, 131072000 blocks
6553600 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=2279604224
4000 block groups
32768 blocks per group, 32768 fragments per group
8192 inodes per group
Superblock backups stored on blocks: 
        32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 
        4096000, 7962624, 11239424, 20480000, 23887872, 71663616, 78675968, 
        102400000

Allocating group tables: done                            
Writing inode tables: done                            
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done     

[root@xxx ~]#

3.挂载

[root@xxx ~]# mount /dev/vdb /data
mount: mount point /data does not exist
[root@xxx ~]# cd /
[root@xxx /]# mkdir data
[root@xxx /]# mount /dev/vdb /data
[root@xxx /]#

4.配置开机自动挂载

修改/etc/fstab文件，在最后一行后面添加

/dev/vdb /data ext4 defaults 0 0

5.重启检查

init 6

重启系统

6.查看

[root@xxx ~]# df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/vda1        50G  2.3G   45G   5% /
devtmpfs        7.8G     0  7.8G   0% /dev
tmpfs           7.8G     0  7.8G   0% /dev/shm
tmpfs           7.8G  320K  7.8G   1% /run
tmpfs           7.8G     0  7.8G   0% /sys/fs/cgroup
/dev/vdb        493G   73M  467G   1% /data
tmpfs           1.6G     0  1.6G   0% /run/user/0
[root@xxx ~]#

可以看到系统已挂载了500G的云盘。
