I am using VROC for CPU RAID with some NVMe drives. I have a RAID 1 array that seems to be having problems. Instead of boring you with the details, I have a more general question.
How does VROC (or RAID 1 controller in general) handle a situation in which the drives have inconsistent bits? There is no way it can know which is correct, because there is no parity bit.
How do most RAID controller handle this?
