The problem here is that the information returned by "lctl device_list" has changed between 2.3 and 2.4. mds-survey calls and parses the output of "lctl device_list".

In b2_3, "lctl device_list" on the MDS returns:

...
  5 UP osc lscratch-OST0000-osc-MDT0000 lscratch-MDT0000-mdtlov_UUID 5
  6 UP osc lscratch-OST0001-osc-MDT0000 lscratch-MDT0000-mdtlov_UUID 5
...

For master, "lctl device_list" on the MDS returns:

...
  8 UP osp lscratch-OST0000-osc-MDT0000 lscratch-MDT0000-mdtlov_UUID 5
  9 UP osp lscratch-OST0001-osc-MDT0000 lscratch-MDT0000-mdtlov_UUID 5
...

I'll upload a patch for mds-survey to match what is done in one of the patches for LU-1303 (http://review.whamcloud.com/4087), when parsing the output to "lctl device_list" look for "osc" and "osp".
