The error message for the test case where we have a quorum node for which no directory name can be generated is different: For twoGbMaxExtentSparse, it complains that it cannot open the extent file. For other (sub)formats, it just notes that it cannot determine the backing file path. Both are fine, but just disable twoGbMaxExtentSparse for simplicity's sake.
