    Description

      After FID on OST is enabled (since 2.4), MDT will request sequence from OST, then precreate (or create) OST objects. Once the current sequence is used up, MDT will request new sequence from OST. During the switch, MDT needs to update precreate file synchronously, (see osp_precreate_rollover_new_seq() ) otherwise it may cause file missing after failover. So we need at least two test cases here.

      1. The system still functional after switching the new sequence.
      2. The files being written are not missing during switching new seqneuce + failover.
