一、查看SSD云盘
?
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | 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
?
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 | 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
?
| 1 | 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
?
| 1 | /dev/vdb /opt ext4 defaults 0 0 |
五、重启检查
使用
?
| 1 | init 6 |
优雅的重启系统。
使用
?
| 1 2 3 4 5 6 7 8 9 | 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。
