 Description   

This issue was created by maloo for Bob Glossman <bob.glossman@intel.com>

This issue relates to the following test suite run: https://testing.hpdd.intel.com/test_sets/7f5500ee-39ba-11e7-8847-5254006e85c2.

The sub-test test_51d failed with the following error:

OST 3 has less objects vs OST 2  (63 < 135

This looks similar to LU-8933. May be a dup. Will leave it to an expert to decide if it's a dup or not.

Info required for matching: sanity 51d

According to b=12622 this test has been intermittently failing since Lustre 1.4, so it should not be considered an error if the object creation is uneven. This will likely need changes to the object allocator, like LU-9, to keep it more balanced over time. In the meantime, it should be added to the ALWAYS_EXCEPT list again or use error_ignore.
