Hello, I wonder what is the "type-0.90.0" superblock and "md-1" superblocks of md and what is the differnce between them? Is it merely some version of kernel md driver ? In case it is so - is there a way to know which is the version of the md superblocks which is in use in my kernel ? I see that in drivers/md/md.c there is an array of super_type with 2 elements, the name of the first is "0.90.0",and the name of the second is "md-1". when running : mdadm --detail /dev/md0 I see: /dev/md0: Version : 00.90.01 .. is this "Version" field is the superblock type ?
