git-annex stores the contents of files inside `.git/annex/objects`. The `git annex add` is failing because it cannot `rename()` the file into that directory, because it is on a different filesystem. Even if it did a more expensive move of the file, it would not do what you want, because all the files would be moved to the `.git/annex/objects` directory, which is stored on your smaller drive.
The way git-annex is intended to be used with multiple drives is this:
* Make a separate git repository on each drive.
* Set up git remotes connecting these repositories together. You don't have to connect them all up, but at least make
the git repository on your main filesystem have a remote for each git repository on other drives.
* Use `git annex sync` to keep the git repositories in sync. (Or do it manually with `git pull`)
* When you want a file to be available in the local repository, use `git annex get $file` to get it.
* When your local repository is getting too full, use `git annex drop` or `git annex move` to flush files
out to the other drive(s).
The [[walkthrough]] goes through an example of adding a removable USB drive this way, but you can do the same thing for
non-removable drives.
> Having two repositories also has the disadvantage that I need two repositories on all other nodes am I right?
No -- you combine the two repositories, so any clone of either one contains all the files in both. Other notes then only need one
repository. However, for another node to be able to get files from both repositories on this node, it will need to have two git remotes configured, one for each repository.
