It's probably still a ways from being finished given how slow lowmem is in comparison, but sadly it found a bunch of problems which regular mode didn't find.
I'm pretty bummed. I just spent way too long recreating this filesystem and the multiple btrfs send/receive relationships from other machines. Too a bit over a week :( It looks like the errors are not major (especially if the regular mode doesn't even see them), but without lowmem --repair, I'm kind of screwed. I'm wondering if I could/should leave those errors unfixed until lowmem --repair finally happens, or whether I'm looking at spending another week rebuilding this filesystem :-/ gargamel:~# btrfs check
