Buyvm 存储块挂载/迈阿密地区测试

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。

官网:点此直达

控制面板: https://manage.buyvm.net/

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 -y

CentOS下

yum install e4fsprogs -y
6、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 /home
7、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/fstab
8、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/vda1       9.8G  841M  8.5G   9% /
tmpfs           242M     0  242M   0% /dev/shm
tmpfs           5.0M     0  5.0M   0% /run/lock
tmpfs           242M     0  242M   0% /sys/fs/cgroup
tmpfs            49M     0   49M   0% /run/user/0
/dev/sda        503G   73M  478G   1% /home
