Can anyone tell me the difference between the different metadata versions for mdadm?
When I try the command
mdadm --examine /dev/sda1, I can't seem to find "preferred superblocks" on version 1.2. This field shows up in metadata version 0.9.
Is there a way to get such metadata information? Or is the output of
mdadm --examine just the information I'm going to get for version 1.2?
