Did you wait for heals to complete before upgrading second node?

We just got split-brain during update to 3.7.13 ;-)This is an interesting point.
Could you please tell me which replica count did you set ?
3
With replica "3" split brain should not occurs, right ?
I guess we did something wrong :-)
Or there is a bug we never found? Could you please share details about what you did?
upgraded to 3.7.13 from 3.7.11 using yum, while at least one VM is running :-)
on all 3 servers, one by one:
yum upgrade
systemctl stop glusterd
than killed glusterfsd processes using kill
and systemctl start glusterd
then next server....
after this we tried to restart VM, but it failed, because we forget to restart libvirtd, and it used old libraries,
I guess this is point where we got this problem.
I'm planning a new cluster and I would like to be protected against
split brains.
