日本vps/linode block storage/linode添加块存储/linode添加磁盘

linode添加块存储教程参考：linode Block Storage添加块存储磁盘教程

如果要我建议的话，当然还是建议根据自己的需求，购买对应的linode套餐，因为默认的套餐磁盘是SSD。个别客户又想要大的磁盘做存储，又不舍得投入更多的钱购买更高配置的SSD，那买低配的linode套餐，然后额外附加一个块存储也是可以的。

下面简单说下教程。老易特意买了个日本VPS，linode日本机房的弄个教程。找易秋网络老易代购linode的话，我这可以免费帮挂载好额外添加的块存储，其实也就是额外挂载下添加的磁盘。

比如默认最低配的是25G磁盘，额外买一块160G的块存储。

root@li1721-227:~# df -h

udev            480M     0  480M   0% /dev
tmpfs            99M   12M   88M  12% /run
/dev/sda         25G  1.1G   22G   5% /
tmpfs           494M     0  494M   0% /dev/shm
tmpfs           5.0M     0  5.0M   0% /run/lock
tmpfs           494M     0  494M   0% /sys/fs/cgroup
tmpfs            99M     0   99M   0% /run/user/0

添加linode块存储后，格式化添加的磁盘，挂载添加的磁盘，并且设置好开机挂载好磁盘：

Volume scheduled for creation.

To get started with a new volume, you'll want to create a filesystem on it:
mkfs.ext4 "/dev/disk/by-id/scsi-0Linode_Volume_block2689"

Once the volume has a filesystem, you can create a mountpoint for it:
mkdir "/mnt/block2689"

Then you can mount the new volume:
mount "/dev/disk/by-id/scsi-0Linode_Volume_block2689" "/mnt/block2689"

If you want the volume to automatically mount every time your Linode boots, you'll want to add a line like the following to your /etc/fstab file:
/dev/disk/by-id/scsi-0Linode_Volume_block2689 /mnt/block2689 ext4 defaults,noatime,nofail 0 2

可以敲命令fdisk -l看看，是多了一块160G的磁盘：

root@li1721-227:~# fdisk -l
Disk /dev/sda: 24.5 GiB, 26306674688 bytes, 51380224 sectors
Disk model: QEMU HARDDISK
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 /dev/sdb: 512 MiB, 536870912 bytes, 1048576 sectors
Disk model: QEMU HARDDISK
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 /dev/sdc: 160 GiB, 171798691840 bytes, 335544320 sectors

Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes

看看挂载好磁盘的磁盘分区情况：
