system chunk is on two devices:
num_stripes 1 sub_stripes 0
num_stripes 1 sub_stripes 1
Maybe it is raid0, but I thought dump super explicitly shows the
profile if it's not single. e.g. SYSTEM|DUP or SYSTEM|RAID1
Only my single profile file systems lack a profile designation in the
super. But I admit I have no raid0 file systems.
