    Description

      This issue was created by maloo for Andreas Dilger <andreas.dilger@intel.com>

      This issue relates to the following test suite run: https://testing.hpdd.intel.com/test_sets/28287b5e-2b40-11e6-acf3-5254006e85c2.

      The sub-test test_248 failed with the following error:

      Test 1: verify that fast read is 4 times faster on cache read
       sanity test_248: @@@@@@ IGNORE (fast read was not 4 times faster: 0.33 vs 1.15):

       sanity test_248: @@@@@@ IGNORE (fast read was not 4 times faster: 0.41 vs 1.45): 
      

      There are also cases where the fast read was "too fast". There is also an error message that needs to be fixed.

      error() without useful message, please fix

            James, you mentioned that you were going to work on a fix for this failure? It looks like the error_ignore is missing an LU ticket number as the first argument, which may as well be this ticket LU-8248.
