Lustre client build: https://build.hpdd.intel.com/job/lustre-b2_5/104
Lustre server build: https://build.hpdd.intel.com/job/lustre-b2_4/73 (2.4.3)

The same failure occurred:
https://testing.hpdd.intel.com/test_sets/57a2934a-7a68-11e4-be53-5254006e85c2

Lustre version check codes need to be added into conf-sanity test 43 on Lustre b2_5 branch.

[Emoly Liu]

The patch landed to 2.6.

[Emoly Liu]

The patch is here http://review.whamcloud.com/10675, to skip conf-sanity.sh test_43 for MDS version < 2.5.58 on master.

[Emoly Liu]

What's more, if we choose to backport to b2_5, the patch http://review.whamcloud.com/#/c/9221/ should be included as well.

[Emoly Liu]

As Oleg said, this issue is related to the master patch http://review.whamcloud.com/5700.
To resolve this issue, we can backport the patch to b2_5, or skip this test for MDS version < 2.5.58 on master since orignal patch made many changes. Which is better?

[Emoly Liu]

I can hit this failure in my local test. I will investigate it.

[Oleg Drokin]

So test 43 that was recently added needs a check added.
original patch was http://review.whamcloud.com/5700
