In this specific case, I do not care if the data is destroyed. Just wanted to know if the disks would still be in sync. For the sync part, I don't believe it would really matter which metadata version I used, the disks would be in sync except for areas where the old metadata was stored. Am I right on this? That is assuming RAID1.
