split brain problem
Hey, I've test that if I initially start 4 replica, than there is high risk to trigger brain splitting(because there is no "first seed node" to avoid brain split). Though we can start the klustrd as 1 replica,than scale out, but this might also happen if the rc restart.
The log,when I initially start 4 replica:
