    Description

      On unlink ost object destroys get delayed until osp_sync_thread decides to cancel unlink records. This makes cascading_rw test to fail due to enospc if OSTs are not big enough as the test consumes disk space faster that osp_sync_thread generates OST_DESTROYs.

      OSTSIZE=200000 SLOW=yes sh parallel-scale.sh should be enough to see the problem.
