I made a little bit of progress recovering this mess, seems
btrfs-progs has improved since I last tried.
# ./btrfs-find-root /dev/mapper/tr5ut-vicep--library
[..]
Well block 317865713664 seems great, but generation doesn't match, have=574372, want=575931
Well block 317874491392 seems great, but generation doesn't match, have=575930, want=575931
Found tree root at 317874626560
Seems like this is a good sign that btrfs-find-root was able to find
the root.
But I'm still stuck on this trying to run btrfs-restore:
# ./btrfs-restore -v -i -u 1 -t 317874626560 /dev/mapper/tr5ut-vicep--library .
checksum verify failed on 317874630656 wanted 8E19212D found FFFFFFA6

checksum verify failed on 317874630656 wanted 8E19212D found FFFFFFA6
Csum didn't match
btrfs-restore: disk-io.c:441:
find_and_setup_root: Assertion `!(ret)' failed.
Aborted
It seems like -i should ignore the csum mismatch, what am I missing?
