1.查看SSD云盘

sudo fdisk -lDisk /dev/vda: 42.9 GB, 42949672960 bytes, 83886080 sectorsUnits = sectors of 1 * 512 = 512 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk label type: dosDisk identifier: 0x635e6c7d   Device Boot      Start         End      Blocks   Id  System/dev/vda1            2048    83886079    41942016   83  LinuxDisk /dev/vdb: 107.4 GB, 107374182400 bytes, 209715200 sectorsUnits = sectors of 1 * 512 = 512 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytes

可以看到SSD系统已经识别为/dev/vdb

2.格式化云盘

sudo mkfs.ext4 /dev/vdb mke2fs 1.42.9 (28-Dec-2013)Filesystem label=OS type: LinuxBlock size=4096 (log=2)Fragment size=4096 (log=2)Stride=0 blocks, Stripe width=0 blocks6553600 inodes, 26214400 blocks1310720 blocks (5.00%) reserved for the super userFirst data block=0Maximum filesystem blocks=2174746624800 block groups32768 blocks per group, 32768 fragments per group8192 inodes per groupSuperblock backups stored on blocks:         32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,         4096000, 7962624, 11239424, 20480000, 23887872Allocating group tables: done                            Writing inode tables: done                            Creating journal (32768 blocks): doneWriting superblocks and filesystem accounting information: done

3.挂载

sudo mount /dev/vdb  /opt

将云盘挂载到/opt目录下。

4.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

5.重启检查

使用

init 6

优雅的重启系统。

使用

sudo df -hFilesystem      Size  Used Avail Use% Mounted on/dev/vda1        40G  3.6G   34G  10% /devtmpfs        1.9G     0  1.9G   0% /devtmpfs           1.9G     0  1.9G   0% /dev/shmtmpfs           1.9G  8.4M  1.9G   1% /runtmpfs           1.9G     0  1.9G   0% /sys/fs/cgroup/dev/vdb         99G   61M   94G   1% /opttmpfs           380M     0  380M   0% /run/user/1000

可以看到系统已挂载了SSD云盘。
