This indicates we're missing profile conversion tests in fstests. I
think it's better to add a test framework/helpers and a full set of
profile conversion tests instead of this raid1->single special case.

e.g.

Define a test case array, which describes what's the src/dst of this
conversion and how many devices this case requires, e.g.

test_cases=(
        # $nr_dev_min:$metadata:$data:$metadata_convert:$data_convert
        "2:single:single:raid0:raid0"
        "2:single:single:raid1:raid1"
        "2:single:single:raid1:raid0"
        "3:single:single:raid5:raid5"
        "4:single:single:raid6:raid6"
        "4:single:single:raid10:raid10"
        "2:raid0:raid0:raid1:raid0"
        "2:raid0:raid0:raid1:raid1"
        "3:raid0:raid0:raid5:raid5"
        "4:raid0:raid0:raid6:raid6"
        "4:raid0:raid0:raid10:raid10"
        "2:raid1:raid0:raid1:raid1"
        "3:raid1:raid0:raid5:raid5"
        "4:raid1:raid0:raid6:raid6"
        "4:raid1:raid1:raid10:raid10"
        "4:raid5:raid5:raid1:raid1"
        "4:raid5:raid5:raid6:raid6"
        "4:raid5:raid5:raid10:raid10"
        "4:raid6:raid6:raid1:raid1"
        "4:raid6:raid6:raid5:raid5"
        "4:raid6:raid6:raid10:raid10"
        "4:raid10:raid10:raid5:raid5"
        "4:raid10:raid10:raid6:raid6"
	<adding more cases>
)

Then, create btrfs in source profile and populate fs with different
kinds of files, compute sha1 digests of these files(fssum?), start
conversion, after conversion compare sha1 digests.

And perhaps we could split the test cases into group and add them to
different tests, in case putting all cases in a single test makes the
test time too long.

Thanks,
Eryu

It's not important to be raid1, the important bit here is any profile to
single. As this is a specific, targeted test. But I do agree that having
a conversion test will be a more robust, long-term solution. Will work
on that.
