- Solved
- Minor
I have 7 drives (all btrfs) in my array they all are readable and work fine in 6.12.14. After the upgrade one drive shows as unmountable. BTRFS command line utilities are unable to detect any filesystem. The array itself seems fine and healthy. Downgrading back to the older OS makes everything work again.
The only error I see in the logs is:
BTRFS error: device /dev/sdj1 already registered with a higher generation, found 113104 expect 125395
Note: I do not have a /dev/sdj
