Although this failures looks like LU-4439, the error message in the client test log is different:

According to the test, it looks like 20940 and 21088 can fix 6844. I will then make a patch to revert http://review.whamcloud.com/20022 .

[Di Wang (Inactive)]

I pushed a patch http://review.whamcloud.com/19489 to see if http://review.whamcloud.com/#/c/20940/ and http://review.whamcloud.com/#/c/21088/ can fix 6844.

[Di Wang (Inactive)]

looks quite similar as LU-7117. will see if they are related.

[Andreas Dilger]

Note this bug should not be closed because of the above patch landing, which only changed the test to run on a single MDS.
