New LUKS device header needs more than 1024 or 4096 bytes - you need space for keyslots. Try reduce device size by 4 Megabytes (and do not forget to reduce fs first): cryptsetup-reencrypt /dev/sda8 --new --reduce-device-size 4M and it should work. I will probably add more descriptive error message here, it is really cryptic.
