阿里云CentOS 7系统挂载SSD云盘的教程

一、查看ssd云盘

sudo fdisk -l 
 
disk /dev/vda: 42.9 gb, 42949672960 bytes, 83886080 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: 0x635e6c7d 
 
 device boot  start   end  blocks id system 
/dev/vda1   2048 83886079 41942016 83 linux 
 
disk /dev/vdb: 107.4 gb, 107374182400 bytes, 209715200 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 

可以看到ssd系统已经识别为/dev/vdb

二、格式化云盘

sudo 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 
6553600 inodes, 26214400 blocks 
1310720 blocks (5.00%) reserved for the super user 
first data block=0 
maximum filesystem blocks=2174746624 
800 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 
 
allocating group tables: done        
writing inode tables: done        
creating journal (32768 blocks): done 
writing superblocks and filesystem accounting information: done  

三、挂载

sudo mount /dev/vdb /opt 

将云盘挂载到/opt目录下。

四、配置开机自动挂载

修改/etc/fstab文件，文件末尾添加

/dev/vdb /opt ext4 defaults 0 0 

五、重启检查

使用

init 6 

优雅的重启系统。

使用

sudo df -h 
filesystem  size used avail use% mounted on 
/dev/vda1  40g 3.6g 34g 10% / 
devtmpfs  1.9g  0 1.9g 0% /dev 
tmpfs   1.9g  0 1.9g 0% /dev/shm 
tmpfs   1.9g 8.4m 1.9g 1% /run 
tmpfs   1.9g  0 1.9g 0% /sys/fs/cgroup 
/dev/vdb   99g 61m 94g 1% /opt 
tmpfs   380m  0 380m 0% /run/user/1000 

可以看到系统已挂载了ssd云盘。
