I'll be needing to split data archives across multiple drives soon.
I've already moved one study to another drive and have its entire
structure appear under /xnat/data through symbolic links. That worked
fine for one study, but now I'll need to "split" a study somehow and
if the new arcNNN could be a link point, it would work wonderfully.

Or are there other suggestions?

Thanks,
Ben

Ben,

Unfortunately, there is no user interface for changing the arc for a project. You could modify it directly in the database, in the arc_project table (current_arc). The Arc info is cached by the server, so you'll either need to restart Tomcat or trigger a refresh (by submitting the Administration -> Default Settings page).

That said, modifying the current_arc is poorly tested. It should work properly in theory. But, if you run into issues, please let me know.

Tim

Thanks Tim. I've changed the db and all seems well.

Ben
