Recently we had a bug where a zoned filesystem could be converted to a
higher data redundancy profile than supported.

Add a test-case to check the conversion on zoned filesystems.

Don't you want to add it in "auto" group, to be a default test?

OK, looks like don't need to check each devices of SCRATCH_DEV_POOL at here :)

+devs=( $SCRATCH_DEV_POOL )

Mkfs with specific options might fail, so better to _fail if mkfs return non-zero,
and better to output the message into .full file, to know what's wrong.

Thanks,
