Description

Sanity test_272a always fails on single OST systems because it checks for a stripe count of two, requiring >1 OST.

results.yml:

            name: test_272a
            status: FAIL
            duration: 1
            return_code: 1
            error: "bad\ final\ stripe\ count:\ 1\ \!=\ 2"

This test should be skipped as others are on configurations with a single OST. For example:

        (( $OSTCOUNT >= 2 )) || skip_env "needs >= 2 OSTs"

as can be seen in ost-pools.sh.
