Thanks for pointing out this issue, I'm not familiar with btrfs at all. Normally this would be a problem and you'd have to find some way to change the UUID in the overlay or whatever, but if it's LUKS encrypted that should solve the problem nicely, you just have to stop the original RAID and close the original LUKS container and then only open the one of the overlay. You should not assemble the original RAID anymore anyhow, anything you write to the array at this point will likely only increase damages. The overlay allows you to experiment in read-"write" mode without actually changing anything on your disks. > The issue is raid6 assembly somehow being wonky. > But at this point we need to hear back from Patrick. Yes, it's quite a mystery, I hope the OP can shed some light on what might have caused this.
