Yeah sure. Thanks

Saurabh, would it be possible for you to submit a patch for b2_5_fe and b_ieel2_0 to skip this test for servers newer than 2.6.50.

The behaviour of this code changed in LU-5424 patch http://review.whamcloud.com/11248 "mdt: allow open by FID to create striping". The check in dot_lustre_fid_permission_check() that is failing was disabled in master for server versions older than 2.6.50:

        if [ $(lustre_version_code $SINGLEMDS) -ge $(version_code 2.6.50) ]
        then # LU-5424
                echo "cp /etc/passwd $MOUNT/.lustre/fid/$fid"
                cp /etc/passwd $MOUNT/.lustre/fid/$fid ||
                        error "create lov data thru .lustre failed"
        fi

We need a patch the old client in order to disable this test for server versions newer than 2.6.50. Also, for interop testing we don't run the b2_6 branch, but only the 2.6.0 release so we would also have to make a 2.6.1 release for this, which will likely not happen.

We can fix this test on b2_5, and that should be done to avoid this spurious test failure.
