Hey, Thanks for the quick reply :-) > Is there anything like unexpected power loss happens? Power loss may have happened. > And would you provide the following data for debugging? > > # btrfs ins dump-super -fFa /dev/mapper/black I attached it. > And further more, what's the device mapper setup for /dev/mapper/black? > Is there anything like RAID here? I think this is the result of luks. "black" is the name I passed to cryptsetup open. > Thanks, > Qu Cheers, marble
