      Hello,

      Current for stripe dir, if 1 MDT is damaged, the whole dir cannot be accessed. We would like to change/improve the implementation to allow access to partial of the stripe dir on undamaged MDTs.

      use case:
      DIR1 cross 4 MDTs, one of the MDT (Not MDT0) is damaged
      1. Create DIR1 as a striped dir cross all 4 MDTs
      2. Umount MDT1
      3. Data on other undamaged MDT should be accessible
