Actually, if it still isn't too far into the reshape, you could use
--revert-reshape. Then it'll reshape back to the original chunk size
what it has done so far. That might be quicker than finishing the
reshape. Then you could reboot into your normal OS.
Whether you finish reshaping, or unreshaping, you need to not be
reshaping at all when you boot into your normal OS, if you can't do the
initramfs console.
