一、查看SSD云盤

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系統(tǒng)已經(jīng)識(shí)別為/dev/vdb

二、格式化云盤

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、掛載

sudo mount /dev/vdb /opt 

將云盤掛載到/opt目錄下。

四、配置開機(jī)自動(dòng)掛載

修改/etc/fstab文件，文件末尾添加

/dev/vdb /opt ext4 defaults 0 0 

五、重啟檢查

使用

init 6 

優(yōu)雅的重啟系統(tǒng)。

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 

可以看到系統(tǒng)已掛載了SSD云盤。

總結(jié)
