    Description

      This bug appeared after commit e8ffe16619baf1ef7c5c6b117d338956372aa752, "LU-884 clio: client in memory checksum",
      unfortunately our tests don't show failure of fsx in sanity-benchmark and sanity-benchmark is not part of every autotest.

      The issue looks like the following:
      /usr/lib64/lustre/tests/sanity-benchmark.sh: line 186: 16826 Bus error (core dumped) fsx -c 50 -p 1000 -S $FSX_SEED -P $TMP -l $FSX_SIZE -N $(($FSX_COUNT * 100)) $testfile

      Example of report (master):
      https://maloo.whamcloud.com/test_sets/02485a3a-45d0-11e1-8d6e-5254004bbbd3

      sanity-benchmark is green but fsx failed as showed above. Recently the same code was landed to the orion and we start experiencing the same issue.
