So if you do not mean to abandon the drbd device along with its meta data, don't touch the meta data. the analogy is something like: "data" == file contents, "meta data" == filename, permissions, access and modification times, ... you remove the "meta data" (directory content), the data (file content) is still there. but you can not really use it anymore... so don't do that.
