    Description

      The namespace LFSCK will check whether the name hash for the name entry under the slave of striped directory matches such shard or not. If not, the LFSCK should migrate the name entry from current MDT to the right MDT. This should be done with async commit supported from DNE2 to avoid lost the name entry or duplicate the name entry and some other recovery troubles.
