问题
I would like to reproduce the network partition scenario with all the three modes - ignore, autoheal and pause_minority.
How can I achieve this? I tried stopping(/sbin/service reboot) one of the nodes of the cluster but this didn't cause any network partitioning. I also tried deleting the mnesia on one node to create inconsistent mnesia across the cluster but that also didn't help.
回答1:
In order to simulate a network partition you can block the outgoing connections using iptables
Suppose you have 3 nodes:
node1 - ip : 10.10.0.1
node2 - ip : 10.10.0.2
node3 - ip : 10.10.0.3
After creating the cluster, go to node 2 for example and
iptables -A OUTPUT -d 10.10.0.1 -j DROP
In this way you blocked the connections and the node will go in network partition.
Then
iptables -F
to restore the network.

Adding more details to above answer:
Execute below command either in node2 or node3 to block the connection from other node(s)
sudo iptables -A INPUT -s 10.10.0.1 -j DROP
To allow the connection from other nodes(s)/delete the firewall rule that we created earlier
sudo iptables -D INPUT -s 10.10.0.1 -j DROP
To view existing firewall rules
iptables --list
Note: In few cluster setup, the net partition occurs only when the nodes whose connections were blocked earlier (via 'iptables' commands) are able to communicate with each other again. So, try block and unblock connections after 60 seconds (which is default 'net_ticktime' value)
