Yes, if you add the other node again and want to reactivate HA simply 
add a VM/CT to HA (via GUI or the command line) and this file will be 
recreated if not existing and everything will work again.

To be honest, that seems like it comes from inside the VM not from PVE.

btw. you can pack a lot of relevant things with journalctl, it has some 
nifty functions, e.g.: you can create a log from a date/time frame:
