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. +"""]]
