This means there are more corruptions in just that one leaf. It's really hard to fix them one by one manually. I'd recommend to go btrfs-restore or use this patchset: https://patchwork.kernel.org/project/linux-btrfs/list/?series=170715 Then mount with ro,rescue=skipbg. Either way, the bitflip is way beyond my imagination. Thanks, Qu > > # btrfs check /dev/sdc1 > Opening filesystem to check... > incorrect offsets 15223 15287 > ERROR: cannot open file system
