Why does my Floating IP look like 10.100.X.X and I can't reach it?

or, you got a message like External network X-X-X-X-X is not reachable from subnet Y-Y-Y-Y-Y. Therefore, cannot associate Port Z-Z-Z-Z-Z with a Floating IP. Why?

You may have selected acs-lab when allocting the Floating IP. This net is experimental and not yet available. Unless you know better, you should always take your Floating IP from the pool called ext-net. Unfortunately the pool selector presets the pool to the first alphabetically. So this happens a lot if you don't pay attention.

What is a volume and what options does it give to me?

If you create a new instance, normally you will get a single fixed sized disk (depending on the flavor) with a maximum of 30 GB. This disk will be stored on the compute node where the instance is launched. There is a fixed relationship between the instance, the disk, and the compute node where the instance is running. A volume, in contrast, is an independent entity which lives on a data-node and can be attached to an instance. You can attach volumes to instances after creation, thus increase the disk space of the instance. When you create a new instance, you can also choose to use a volume as single root file system (no additional miunts), which overrides the fixed compute node bound disk and adds flexibility to the instance (instance can be live migrated, disk can be as large as your quota can afford and can also be increased in disk size later on).
