Anyone else getting corruptions with 4.11? I happily switch back to 4.10.17 or even 4.9 if that is the case. I may even do so just from your reports. Well, yes, I will do exactly that. I just switch back for 4.10 for now. Better be safe, than sorry. I know how you feel, Marc. I posted about a corruption on one of my backup harddisks here some time ago that btrfs check --repair wasn´t able to handle. I redid that disk from scratch and it took a long, long time. I agree with you that this has to stop. Before that I will never *ever* recommend this to a customer. Ideally no corruptions in stable kernels, especially when its a .6 at the end of the version number. But if so… then fixable. Other filesystems like Ext4 and XFS can do it… so this should be possible with BTRFS as well. Thanks, -- Martin
