Hey guys, Today I experienced my first checksum error just out of the blue - and it's not just the 'csum + 1 = private' issue, it's a completely different one. Because of this, I am unable to retrieve the data off the drive, even with nodatasum enabled - I simply get an I/O error. Here's the dmesg output: [149423.845177] btrfs: setting nodatasum [149423.850339] Btrfs detected SSD devices, enabling SSD mode [149432.094728] btrfs csum failed ino 259 off 26701824 csum 3875867041 private 371726550 [149432.117938] btrfs csum failed ino 259 off 26701824 csum 3875867041 private 371726550 [149432.118340] btrfs csum failed ino 259 off 26701824 csum 3875867041 private 371726550 [149432.125671] btrfs csum failed ino 259 off 26701824 csum 3875867041 private 371726550 [149432.126075] btrfs csum failed ino 259 off 26701824 csum 3875867041 private 371726550 [149432.135671] btrfs csum failed ino 259 off 26701824 csum 3875867041 private 371726550 I would really like to have the files on the drive retrieved in their entirety, but if that is not possible then that is also OK. Consider this a bugreport and a question on how to retrieve the data now.
