Description

This issue was created by maloo for Bob Glossman <[e-mail]>

This issue relates to the following test suite run: https://testing.hpdd.intel.com/test_sets/9e3e0324-ef35-11e4-9a16-5254006e85c2.

The sub-test test_8 failed with the following error:

opendevunlink /mnt/lustre/f8.sanityn /mnt/lustre2/f8.sanityn

This looks a bit like LU-4164, but isn't seen during interop tests.
I'm raising it as a new bug. An expert may decide it's a dup.

Info required for matching: sanityn 8

So looks like the real error code hidden in mdt_intent_opc(). We may catch it after http://review.whamcloud.com/#/c/11650/.
