阿里云购买的第2块云盘默认是不自动挂载的，需要手动配置挂载上。
1.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
2.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
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 -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。
