But I'm still stuck on this trying to run btrfs-restore: # ./btrfs-restore -v -i -u 1 -t 317874626560 /dev/mapper/tr5ut-vicep--libra= ry . checksum verify failed on 317874630656 wanted 8E19212D found FFFFFFA6 checksum verify failed on 317874630656 wanted 8E19212D found FFFFFFA6 checksum verify failed on 317874630656 wanted 491D9C1A 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.
