The Azure VM table...

https://www.windowsazure.com/en-us/pricing/details/#header-2

...says that, for example, a Medium Instance comes with 490GB of local storage. So I was expecting the usual 30GB Azure BLOB OS disk, and then a 490GB /mnt/resource.

But no:

$ df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup-lv_root
                       28G  1.7G   25G   7% /
tmpfs                 1.7G     0  1.7G   0% /dev/shm
/dev/sda1             485M   68M  392M  15% /boot
/dev/sdb1             133G  188M  126G   1% /mnt/resource

That's on the CentOS image, but it's the same for other images.

Am i missing something? I don't see the space in a volume group or anything, and there are no sd* devices that aren't mounted.

Neil Mackenzie 在评论中的回答似乎是正确的

所有 Windows Azure IaaS VM 都带有两个磁盘 - 一个由保存在 Windows Azure Blob 存储中的 VHD 支持的 OS 磁盘和一个物理连接到托管服务器的临时磁盘。这个临时磁盘是真正的临时磁盘，如果 VM 被解除分配（在门户或 API 上关闭）或移动以进行服务器修复，则其上的任何内容都将丢失。对于 Linux VM，此临时磁盘 /dev/sdb。
