When trying to shutdown a specific node by example pexgal001-dev3, pexgal002/3 respectively detect the node is out of the cluster and behave as designed, but when pexgal001-dev3 is now up again this caused a split brain situation between the donor (pexgal003-dev3) and the joining node (pexgal001-dev3) leaving only 1 node up and running in the cluster (pexgal002-dev3)
Here is the full log of pexgal002-dev3 and pexgal003-dev3 (donor) when the joining pexgal001-dev3 node is down and then up.

I have 3 Percona Galera XtraDB Cluster with 3 nodes pexgal001-dev3 pexgal002-dev3 pexgal003-dev3
version of the server
When trying to shutdown a specific node by example pexgal001-dev3, pexgal002/3 respectively detect the node is out of the cluster and behave as designed, but when pexgal001-dev3 is now up again this caused a split brain situation between the donor (pexgal003-dev3) and the joining node (pexgal001-dev3) leaving only 1 node up and running in the cluster (pexgal002-dev3)
Here is the full log of pexgal002-dev3 and pexgal003-dev3 (donor) when the joining pexgal001-dev3 node is down and then up.
