[Maria-discuss] New Question: Simple cluster two nodes, error.
Hello,
A new question has been asked in "MariaDB FAQ" by maximilianodipietro: -------------------------------- Hi people, i have a two nodes cluster of MariaDb, and i need some help, i have this simple script to do a solve failover, the script works like this: if the master node dies, the script kills the slave and restart it as master, and then the master as slave when the script detects that the process is down, here's the code:
---------------------------------------------------------------------------------------------------------------------------------- #!/bin/bash

hum, must check but i think that galera cluster is 3+ nodes, i only tested with 3+ here, didn't tested with 2 nodes yet

Hi,
1) There's no master and no slave, there's a totally different thing: Primary Component. It is the part of the cluster that is allowed to modify data. So you either start a new cluster or join a node to the primary component. If you join a node to a non-primary component, then it is in non-primary component and that's what you get.
131211 20:05:05 [ERROR] WSREP: failed to open gcomm backend connection: 110: failed to reach primary view: 110 (Connection timed out)
by default it refuses to stay there and shuts down (so that you have a chance to connect it to primary).
2) If the cluster partitions (connection between nodes lost) primary becomes the component with ABSOLUTE majority of nodes. In your case of 2 nodes there can be no absolute majority. When one node dies the other finds itself in a so-called "split-brain" situation and becomes non-primary. That's what seem to have happened in your situation and that's the reason to require 3 nodes.
3) There are different ways to get out of this situation: - restart the cluster from scratch. - SET GLOBAL wsrep_provider_options='pc.bootstrap=1' - assign a greater weight to one of the nodes (beforehand) - force a node to ignore split-brain (beforehand) All have different tradeoffs. I'd recommend the second option.
Regards, Alex
