Update your kernel to 3.17.2 - that takes care of all the big known 3.16/17 issues in general. 2. Run btrfs check using btrfs-tools 3.17. That can clean up the broken snapshots in your filesystem. That is fairly likely to get your filesystem working normally again. It worked for me. I was getting some balance issues when trying to add another device and I'm not sure if 3.17.2 totally fixed that - I ended up cancelling the balance and it will be a while before I have to balance this particular filesystem again, so I'll just hold off and hope things stabilize. -- Rich -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
