Rerun sanity with the latest master build, cannot reproduce

Btw: we still need fix SINGLEMDS issue in the test script, but probably not in this time frame.

Hmm, I checked all error log of DNE upgrade error ticket, 3234, 3235, 3236. It seems all related with SINGLEMDS is not defined. Interesting, I thought SINGLEMDS is defined in testframe.sh by default. Sarah, Could you please run this again with lastest master to make sure SINGLEMDS is defined, if it is still failed, I will investigate the t-f to see. In the mean time, I will close 3234 and 3235, just leave this open.

I suspect this is just fallout from a previous test failure.

Also need to know the lustre build version to know if this has been fixed by http://review.whamcloud.com/6106
