最近Buyvm 新增迈阿密地区，目前用的人比较少，应该炸得不会很厉害。

1、挂载
1、查看磁盘基本信息
fdisk -l输入后信息如下
root@localhost:~# fdisk -l
Disk /dev/vda: 10 GiB, 10737418240 bytes, 20971520 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
Disklabel type: dos
Disk identifier: 0x132f3779
Device Boot Start End Sectors Size Id Type
/dev/vda1 * 2048 20969215 20967168 10G 83 Linux
Disk /dev/sda: 512 GiB, 549755813888 bytes, 1073741824 sectors
Disk model: SLAB
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
2、对新添加的硬盘进行分区
fdisk /dev/sda按以下顺序输入
root@localhost:~# fdisk /dev/sda
Welcome to fdisk (util-linux 2.33.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
The old ext4 signature will be removed by a write command.
Device does not contain a recognized partition table.
Created a new DOS disklabel with disk identifier 0xea7e50e8.
Command (m for help): n #输入n
Partition type
p primary (0 primary, 0 extended, 4 free)
e extended (container for logical partitions)
Select (default p): p
Partition number (1-4, default 1): 2 #输入2
First sector (2048-1073741823, default 2048): #回车默认
Last sector, +/-sectors or +/-size{K,M,G,T,P} (2048-1073741823, default 1073741823): #回车默认
Created a new partition 2 of type 'Linux' and of size 512 GiB.
Command (m for help): w #输入w
The partition table has been altered.
Calling ioctl() to re-read partition table.
Syncing disks.
3、查看新分区
fdisk -l出现新分区如下
root@localhost:~# fdisk -l
Disk /dev/vda: 10 GiB, 10737418240 bytes, 20971520 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
Disklabel type: dos
Disk identifier: 0x132f3779
Device Boot Start End Sectors Size Id Type
/dev/vda1 * 2048 20969215 20967168 10G 83 Linux
Disk /dev/sda: 512 GiB, 549755813888 bytes, 1073741824 sectors
Disk model: SLAB
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0xea7e50e8
Device Boot Start End Sectors Size Id Type
/dev/sda2 2048 1073741823 1073739776 512G 83 Linux
4、查看数据块编号
ls /dev/disk/by-id/诸如“scsi-0BUYVM_SLAB_VOLUME-9812”编号的即为挂载的存储块
5、格式化
mkfs.ext4 -F /dev/disk/by-id/存储块编号如出现错误：mkfs: failed to execute mkfs.ext4: No such file or directory 则需要安装 e4fsprogs
Debian/Ubuntu下
apt-get install e4fsprogs -yCentOS下
yum install e4fsprogs -y6、创建文件夹挂载或直接挂载（此处我直接挂载在/home目录下）
mount -o discard,defaults /dev/disk/by-id/数据库编号 /home7、设置开机或重启自动挂载
echo '/dev/disk/by-id/数据库编号 /home ext4 defaults,nofail,discard 0 0' | sudo tee -a /etc/fstab8、查看挂载情况
df -h结果如下，即为挂载完成
root@localhost:~# df -h
Filesystem Size Used Avail Use% Mounted on
udev 228M 0 228M 0% /dev
tmpfs 49M 1.6M 47M 4% /run

/dev/sda 503G 73M 478G 1% /home
