The system uses ECC memory and edac-util has not reported any errors.
However, I will run a memtest anyway.
So it should not be the memory problem.
BTW, what's the current generation of the fs?
# btrfs inspect dump-super <device> | grep generation
The corrupted leaf has generation 2862, I'm not sure how recent did the
corruption happen.
generation 358392
chunk_root_generation 357256
cache_generation 358392
uuid_tree_generation 358392
dev_item.generation 0
I don't recall the last time I ran a scrub but I doubt it has been
more than a year.
I am running 'btrfs check --init-csum-tree' now. Hopefully that clears
everything up.
No such luck:
