linode添加塊存儲教程參考：linode Block Storage添加塊存儲磁盤教程

如果要我建議的話，當然還是建議根據自己的需求，購買對應的linode套餐，因為默認的套餐磁盤是SSD。個別客戶又想要大的磁盤做存儲，又不舍得投入更多的錢購買更高配置的SSD，那買低配的linode套餐，然后額外附加一個塊存儲也是可以的。

下面簡單說下教程。老易特意買了個日本VPS，linode日本機房的弄個教程。找易秋網絡老易代購linode的話，我這可以免費幫掛載好額外添加的塊存儲，其實也就是額外掛載下添加的磁盤。

比如默認最低配的是25G磁盤，額外買一塊160G的塊存儲。

tmpfs            99M     0   99M   0% /run/user/0

添加linode塊存儲后，格式化添加的磁盤，掛載添加的磁盤，并且設置好開機掛載好磁盤：

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，是多了一塊160G的磁盤：

root@li1721-227:~# fdisk -l

看看掛載好磁盤的磁盤分區情況：
