    Description

      The layout EA storing on the MDT-object records not only the file layout but also some information which indicates the layout EA owner, such as lov_mds_md.lmm_oi. They are generated from MDT-object FID, with them we can know which file the layout EA belongs to. In the LFSCK phase II, we need to verify whether such information in the layout EA is correct or not by re-caculating from the MDT-object FID. If inconsistency is found, trust the MDT-object FID rather than the FID information in the layout EA, which has not been maintained over backup/restore and is mostly used for informational purposes until now.
