Thanks for your answer.

I've only read about scrub in a mirorr situation, as per
https://blogs.oracle.com/wim/entry/btrfs_scrub_go_fix_corruptions

It's a single device here, so if there are problems, I'm not sure how scrub
will be able to fix them.
Would you like me to go ahead and do it anyway?

And before I further remove potential debug state
1) what about this problem?
btrfs-image: btrfs-image.c:518: create_metadump: Assertion `!(ret < 0)'
failed.
Aborted

2) anything else you want me to get off my filesystem before I scrub it?
