Vultr赠送的50G Block Storage使用教程

Vultr最近改版了,看起来不太习惯,不过还是不丑的。Vultr今年应该会发展更好,又要新上个亚洲机房。这不又来做活动了,每个用户能申请免费50G的硬盘
50G 硬盘是SATA-based with an SSD cache
目前只可以挂在在 NY/NJ节点
Attach block storage as a secondary drive to instances in NY/NJ.
好多人说赠送的50G是永久的,但是我要明确的告诉你不是永久的,只是在BETA期间。
官方说明:
During the Beta period, Block Storage will be available in our New Jersey location for no additional charge.

  • 第三步:attach Block Storage

  • 第四步:分区,格式化,mount

#分区
parted -s /dev/vdb mklabel gpt
parted -s /dev/vdb unit mib mkpart primary 0% 100%

#格式化
mkfs.ext4 /dev/vdb1
mkdir /mnt/blockstorage
#开机自动挂载
echo >> /etc/fstab
echo /dev/vdb1               /mnt/blockstorage       ext4    defaults,noatime 0 0 >> /etc/fstab
mount /mnt/blockstorage

#查看:
fdisk -l

[root@vultr ~]# fdisk -l

删除VPS后,保存在Block Storage的数据并不会消失,保存时长未知,最好备份一份,VPS脚本自动备份数据到Dropbox 只需要新建VPS,重新挂载即可,正确的挂载方式:

新建VPS,连接Block Storage,点击:Attach按钮,系统会自动链接,链接完成后,VPS会自动重启,重启完成后执行以下命令,记得不要执行上面的命令,上面的命令是第一次挂载需要格式化Block Storage这个数据盘:
