We are doing lookup everywhere, and building up a dict of the extended attributes of a file as we traverse each sub volume across the hot and cold tiers. The length field of one of the EC keys is corrupted.

Not clear why this is happening.. I see no tiering relationship as of yet, its possible the file is being demoted in parallel to the foreground script operation. 

The test runs fine on my machines.  Does this reproduce consistently on one of the Jenkins machines? If so, getting onto it would be the next step. I think that would be preferable to masking this test case.
