Description

This issue was created by maloo for Andreas Dilger <[e-mail]>

This issue relates to the following test suite run:
https://testing.whamcloud.com/test_sets/c2e89b09-33e9-49d2-b82e-61b6bfcbce00

test_65n failed with the following error during interop testing with 2.14 servers and master clients:

== sanity test 65n: don't inherit default layout from root for new subdirectories ==== 19:19:58 (1729538398)

It looks like this is a new testing interop issue introduced in commit v2_14_57-22-g6e59408f1a from patch https://review.whamcloud.com/34536"LU-12130 lod: make pool inheritance policy more consistent"

Hi vsaveliev, could you please make a patch to skip the extra checking at the end of sanity test_65n when running with older servers that was added in your LU-12130 patch. It is causing interop test failures.

Normally this is not hit in autotest because test_65n is skipped during interop testing due to MDSCOUNT < 2. However, now that I realize we are not running interop testing with multiple MDTs I'm going to ask that this be enabled to have better test coverage.
