      Description

      While running recovery-mds-scale test failover_mds (MDS failed over 1 time), client load on one of the clients failed as follows:

      2014-08-16 20:44:59: dd run starting
      + mkdir -p /mnt/lustre/d0.dd-shadow-41vm5.shadow.whamcloud.com

      2014-08-16 20:52:06: dd failed
      

      Console log on the client:

      LustreError: 3715:0:(vvp_io.c:1081:vvp_io_commit_write()) Write page 1213956 of inode ffff88007ccedb78 failed -28
      

      Maloo report: https://testing.hpdd.intel.com/test_sets/acafc288-26a6-11e4-84f2-5254006e85c2

      The failure was reported in LU-3326 before. However, Lustre b2_5 build #80 already contained patch http://review.whamcloud.com/11425. So, more fixup is needed to resolve the failure.
