Thanks. Actually I'm past that, I'm doing 
./btrfs check --init-csum-tree /dev/mapper/dshelf1
that's the one that's been running for days.

Are you saying init-csum-tree was moved to rescue which does run faster,
and after that I should run the last step, check --repair, that you
suggested?

Thanks,
Marc
