8.3.1 Example STONITH Resource
Configurations
In the following, find some example configurations written in the syntax of the
crm
command line tool. To apply them, put the sample in a text file (for example,
sample
.txt
) and run:
crm < sample.txt
For more information about configuring resources with the
crm
command line tool,
refer to Chapter 5, Configuring Cluster Resources From Command Line (page 59).
WARNING: Testing Configurations
Some of the examples below are for demonstration and testing purposes only.
Do not use any of the
Testing Configuration
examples in real-life cluster
scenarios.
Example 8.1 Testing Configuration
configure
primitive st-null stonith:null \
params hostlist="node1 node2"
clone fencing st-null
commit
Example 8.2 Testing Configuration
An alternative configuration:
configure
primitive st-node1 stonith:null \
params hostlist="node1"
primitive st-node2 stonith:null \
params hostlist="node2"
location l-st-node1 st-node1 -inf: node1
location l-st-node2 st-node2 -inf: node2
commit
This configuration example is perfectly alright as far as the cluster software is concerned.
The only difference to a real world configuration is that no fencing operation takes
place.
