The question I have is why is there IMSM meta data on sdc2 at all? IMSM metadata sit at the end of a block device. So I figure that sdc2 is the last partition, and by some wird circumstance it's so large that it includes the last sectors of the physical disk where the metadata resides. That would be a bad idea, a dd if=/dev/zero of=/dev/sdc2 would wipe not only the partition but also the RAID meta data.
