Should I try btrfs-zero-log? Or should I try btrfsck? Or something else?The standard advice concerning btrfs check (aka btrfsck) is that running it without --repair or similar won't hurt as in that case it's read-only, but by the same token, it won't help, except possibly to give you an idea of what's wrong.
fwiw, this is the output of btrfsck: http://cwillu.com:8080/86.136.116.221/2 > <snip helpful advice>Thanks for the helpful info, I will work through it. It would be nice to be able to recover the filesystem, but if I can't recover the filesystem it wouldn't be the end of the world as I have a backup from a few days before the incident. Even if I can't recover the filesystem, if reporting this issue helps btrfs be more robust in the future that would be a good outcome. To that end I have made a copy of the filesystem with btrfs-image which I can supply if necessary.
