@crosbymichael -- could you give some comments, especially about the last section?
Why can't volumes be backed-up or mounted from special devices? It seems like they should be able to.

👍 ping @metalivedev

Also, I was discussing with @metalivedev that when I shared the volume among two containers, it seemed to be copying instead of using the same volume. When I change the data from one container, I don't see that change on the other one and vice-versa. I didn't dig into the code to check that, but it should be a copy or the same volume? @creack @crosbymichael

As I spoke to @crosbymichael it's the same volume. But I'm getting the following behavior:

root@precise64:/home/vagrant# docker inspect f760a2992eba | grep /lib/couchdb
            "/var/lib/couchdb": {}
        "/var/lib/couchdb": "/var/lib/docker/volumes/ccdace3a1eaa30da55133b825ff5e1707696b48f73cc65f2b29452a5ffff3d63/layer"
        "/var/lib/couchdb": true

Both containers have the same volume. But I was experiencing some caching issues with CouchDB that seemed to be different volumes. I'll update the documentation with the correct info.

Thanks

@rogaha What are the run commands that you are using?

@crosbymichael, I was using the browser interface to change the values. But I was accessing them from a different physical machine using the browser as well.

Nice @rogaha ! Thanks for taking care of this.

You are welcome! :)

Let's how it goes after @crosbymichael and @metalivedev reviews! I keep working on "missing parts" of the documentation!

You'll also need to add this to the to sources/use/index.rst to get it to show up.
I'd say add it to the index and remove lines 75-end (until we can get some core engineering input on how they're implementing it) and you'll be good.

Hi @metalivedev,

Thanks for your comments. I'll do that and update the PR.
