Need a call of _require_scratch_dev_pool_equal_size here

echo the $mkfs_opts to $seqres.full is useful for debug purpose, so if
some profile config fails we know what config is failing.
echo "Test $mkfs_opts" >>$seqres.full
> + _scratch_pool_mkfs $mkfs_opts >>$seqres.full 2>&1 || _fail "mkfs failed"
Continue to test next profile config if mkfs failed, _fail breaks out
the whole test.

I don't think the _fail here is necessary either.

Don't _fail here, just echo error messages to break golden image. Better
to append the error message to $seqres.full too, for debug purpose.
