Logmessage: Error: Librados obj: a9cd162ed243bf5b8f150000c86de11e, could not be removed

In case the backup of a users mail fails, due to an invalid read of a source mail (invalid size / corrupt data),
the copy from mdbox->rbox terminates.

In this case, a log message like;
Error: Librados obj: a9cd162ed243bf5b8f150000c86de11e, could not be removed
will be written to the log file.

In this case the message is misleading, because the object was not written to the ceph storage.

possible solutions:

1. do a additional stat before the ceph delete (cleanup)
2. remember, if a ceph-write was called for this object.

if delete returns with ENOENT no error will be written to log file.
