Hit a lot similar error in the interop testing between 2.5.1 server and master client:

Nathaniel is looking into this one

[Nathaniel Clark]

This was fixed on master as an addon to patch http://review.whamcloud.com/6339
see the last line of comment:

Also remove client eadatasize check in mdt xattr packing because
as said above client can handle -EOVERFLOW.

I believe this is what is tripping in this case.

[James A Simmons]

Your patch is less intrusive but I have to say back porting http://review.whamcloud.com/6339 is more desirable for us. The full patch from LU-3338 will also address the contention issues with vmalloc on the clients we see as well.

[Nathaniel Clark]

Patch 6339 on LU-3338 is generally unrelated to this issue, it just happens to include the fix for this almost as an afterthought. It was infact added in rev 13 of that patch to fix an autotest issue.

[James A Simmons]

You are right. I was thinking about the easy of cherry picking but that is not the case for the LU-3338 patch anyways. The LU-3338 patch uses linux apis instead of the cfs_ wrappers which needs to be fixed up for b2_5.
Just need to watch the order of landing.

Test for Change, 9812 was retriggered just now.

[Jodi Levi (Inactive)]

Test retriggered today.

[Nathaniel Clark]

Since this issue is present in 2.5 and the patch 9812 is a back-ported form master to b2_5, I've changed the Affected and Fix version to the appropriate 2.5.x versions.

[Peter Jones]

Landed for 2.5.2
