Hello,

Did you wait for synchronization to complete before plugging second server off? 
Usually it need 10-15 minutes. Sometimes faster.

I have a problem about split-brain, details as below:

PC1 and PC2 is AFR, stored a file 1.txt

1. write "123" to 1.txt, then 1.txt in pc1 is same with 1.txt in PC2, content 
is "123"

2. PC1  network disconnect, write "45" to 1.txt, then  content of 1.txt in pc1 
is "123",  
  
   content of 1.txt in pc2 is "12345"

3. PC2  network disconnect, but PC1 network is good, write "67" to 1.txt, then  
content of 1.txt in pc1 is "12367",  
  
   content of 1.txt in pc1 is "12345"
