Description

conf-sanity test_72 calls tries to "tune MDT with '-O extents' by calling

$TUNE2FS -O extents $(mdsdevname $num)

Yet, this generates an error. In the client test_log, we can see:

tune2fs: No such file or directory while trying to open /dev/lvm-Role_MDS/P1
Couldn't find valid filesystem superblock.
tune2fs 1.42.12.wc1 (15-Sep-2014)

The test will continue without error even though the call to tune2fs fails.
Here is an example of a test session that conf-sanity test 72 PASSes, but tune2fs fails https://testing.hpdd.intel.com/test_sets/265a72ae-6dbf-11e4-9c5a-5254006e85c2

The call to tune2fs should be made on the MDS(s) and we should check the return code of tune2fs.

I will upload a patch.
