Description

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

This issue relates to the following test suite run: https://maloo.whamcloud.com/test_sets/a02cc9b2-9ec5-11e2-975f-52540035b04c.

The sub-test test_17m failed with the following error:

e2fsck should not report error upon short/long symlink MDT: rc=4

Aftter upgrade from 1.8.9 to 2.4, adding a new MDT, hit following error. I found LU-2097 has the similar error while it has been landed:
