This issue relates to the following test suite run: http://maloo.whamcloud.com/test_sets/1d5f9fd8-5c6a-11e3-9d08-52540035b04c.

The sub-test test_47 failed with the following error:

This test took 3600s and failed with timeout, cannot find error logs. I checked
a PASS conf-sanity run on zfs, the same sub test takes about 134s to complete:

Minh retriggered the test of Change, 9875 on Shadow today.

We are talking about back port of http://review.whamcloud.com/8997, right? I can do that.

Somebody needs to backport the patch from lu-4413 as it could not be cleanly cherry-picked to b2_5

[Sarah Liu]

Hi Jodi,
No, I didn't see this issue in tag-2.5.57 testing

[Jodi Levi (Inactive)]

Sarah,
Did you hit this on the 2.5.57 tag testing?

[Mikhail Pershin]

set ticket as replated to LU-4413 just because of the similar symptoms

[Mikhail Pershin]

Last two issues were happened in branches without LU-4413 fix mentioned in Fan Yong comment. We have to port http://review.whamcloud.com/8997 to the b2_5 it seems

[Bob Glossman (Inactive)]

may be the same issue, seen in b2_5:
