默认实例存储的m1.small不存在 [英] default instance storage for m1.small does not exist
问题描述
我跑DF -h并得到了：
的/ dev / xvde1 6.0G 1.9G 4.1G 32％/
没有828M 0 828M 0％的/ dev / shm的
和猫的/ etc / fstab文件：
LABEL = _ / / EXT4默认值1 1
为/ dev / xvdb到/ mnt ext3的默认值，背景= system_u：object_r：usr_t：S0 0 0
没有的/ proc PROC默认值0 0
无/ SYS sysfs的默认值0 0
没有的/ dev /其中pts devpts GID = 5，模式= 620 0 0
没有的/ dev / shm的tmpfs的默认0 0
为/ dev / sda3的无掉期SW，评论= cloudconfig 0 0
lsblk的输出：
名少校：分企业规模RO类型MOUNTPOINT
xvde1 202：65 0 0 6G硬盘/
xvde3 202：67 0 896M 0磁盘[SWAP]
我想的/ dev / xvdb是大约160 GB的我的实例存储。不过，我没有看到这个设备时，我在/ dev /.
有没有人知道我怎么能得到这个实例存储安装？
非常感谢
如果你从微观实例（或者说只有EBS存储任何实例）升级，它不会被默认包含。 在任何情况下，你可以通过创建实例的快照，并重新发动添加。您可以在快照页面上添加，或在启动向导时，从现有的AMI启动。
- 开启EC2 Web管理控制台。
- 点击上实例左侧，选择您的实例，单击操作下拉菜单，然后选择创建图像。
- 在快照页面中输入一个名称和描述。您可以添加实例存储在这里，如果你喜欢或更高版本，当您启动AMI。点击添加音量按钮。选择备份存储0作为类型，和任何设备路径你喜欢。然后点击创建映像。
- 转至下的AMI在EC2管理控制台左边网站上的图片部分。
- 在等待你的新形象的AMI状态为可用。
- 选择新的AMI，单击启动顶部，并通过推出向导（经过的步骤，这样你就可以将它设置相同的安全组和密钥对作为当前服务器）。
- 在第4步，你有机会再次修改卷。确保零备份存储0被列为第二卷。
- 完成向导并等待发射。当你登录DF -h会显示音量。
有人推荐快照之前停止实例，但我从来没有遇到过的问题。在我的经验（使用ELB前方），而速动是由在服务器通常长达10分钟不可用。

I ran df -h and got:
/dev/xvde1 6.0G 1.9G 4.1G 32% /
none 828M 0 828M 0% /dev/shm
and cat /etc/fstab:

output of lsblk:

I suppose /dev/xvdb to be my instance storage of around 160 GB. However, I do not see this device when I run ls -a on /dev/.
Does any one know how I can get this instance storage mounted?
thanks so much
If you upgraded from a micro instance (or any instance that only has EBS storage), it won't be included by default. In any case, you can add it by creating a snapshot of your instance and relaunching. You can add it on the Snapshot page, or in the Launch wizard when launching from an existing AMI.
- Open EC2 Web Admin Console.
- Click on Instances on the left, select your instance, click the "Actions" dropdown, then select "Create Image".
- On the snapshot page enter a name and description. You can add the Instance Store here if you like or later when you launch the AMI. Click the Add Volume button. Select "Instance Store 0" as the type, and whatever device path you like. Then click "Create Image".
- Go to AMIs under the images section on the left site of the EC2 Admin Console.
- Wait for the AMI status of your new image to be "available".
- Select the new AMI, click Launch at the top and go through the launch wizard (go through the steps, so you can set it up with the same security group and key pair as your current server).
- On step 4 you have a chance to modify the volumes again. Make sure "Instance Store 0" is listed as the second volume.
- Finish wizard and wait for launch. When you login df -h will show the volume.
Some recommend stopping the instance before the snapshot, but I've never had a problem. In my experience (using an ELB in front) the server is usually unavailable for up to 10 minutes while the snap is made.
