    Description

      In current striped directory implementation, if one stripe MDT failed, the striped directory will not be able to access, which seems unacceptable. So in this case

      1. lfs getdirstripe should indicate which stripe is failed.
      2. the left stripes should be able to be accessed, and can be migrated to a new directory.
      3. creating the file/dir on the failed stripe should fail, though it should succeed on other stripes.

      Other suggestions? If some else already create the ticket, please close this one. Thanks.
