[LU-1816] OI scrub should skip to process the new created objects for once

Thu, 6 Sep 2012 23:30:36 +0000

For performance optimization, the OI scrub will not process the objects which are created after the latest MDT mounts. Those objects will be marked as the flag "I_LUSTRE_NOSCRUB" in RAM. On the other hand, if the object with "I_LUSTRE_NOSCRUB" is used/cached in RAM for very long time, then OI scrub has no chance to process it even if there has been inconsistency happened until the MDT remount. So as compromise, the OI scrub will skip the new created objects for once when the first accessing.
