Your config file is completely corrupted.  If you format Sheepdog on
another machine and copy the created config file to both of cluster
nodes, I think you can fix your Sheepdog.

I wonder why your config file is corrupted.  Perhaps, we should use a
more stable way to read/write the config file (e.g. using BerkeleyDB).

Thanks,
