Each of the file's +underlying objects must be removed independently. If these objects were removed +immediately, the client would have to send ``size_of_file / stripe_size * +replication_count`` messages. This would consume significant bandwith and would +slow the client unacceptably. If snapshots exist, their existence can prevent +the deletion of objects associated with them. + +In these cases, such files are (1) marked as deleted on the MDS and (2) deleted +lazily. |
