Please provide the dump of that tree blocks. # btrfs ins dump-tree -b 859701248 /dev/sdd1 It looks like that tree block has something wrong with it. Thus kernel reject to accept the data.

If it's truely corrupted by whatever the reason, you'd better check your memory, as it looks like a bit flip. Thanks, Qu > > Kind Regards, > Jim >
