-=========================
- CephFS delayed deletion
-=========================
-
-When you delete a file, the data is not immediately removed. Each
-object in the file needs to be removed independently, and sending
-``size_of_file / stripe_size * replication_count`` messages would slow
-the client down too much, and use a too much of the clients
-bandwidth. Additionally, snapshots may mean some objects should not be
-deleted.
-
-Instead, the file is marked as deleted on the MDS, and deleted lazily.
