On my BTRFS filesystem, I have a problem with block id #43231330304.
BTRFS critical (device sda2): corrupt leaf, slot offset bad: block=43231330304,root=1, slot=47
I want to know which files are part of this block. How to do this?

To identify the corrupted files, first run:
btrfs scrub status /mount-point
then check the path in dmesg:
BTRFS: i/o error at logical 167135232000 on dev /dev/sda2, sector 213189792, root 5, inode 2963892, offset 7700480, length 4096, links 1 (path: /home/foo...)

It seems like you have to first start a scrub via
btrfs scrub start /mount-point. – nealmcb Jul 25 '21 at 00:43
find /mount-point -type f -exec cp {} /dev/null \;seems an option, see http://superuser.com/questions/858237/finding-files-with-btrfs-uncorrectable-errors – Martin Monperrus Apr 23 '15 at 18:01
