5.14 Testing with Shadow
Configuration
NOTE: For Experienced Administrators Only
Although the concept is easy, it is nevertheless recommended to use shadow
configuration only when you really need them, and if you are experienced with
High Availability.
A shadow configuration is used to test different configuration scenarios. If you have
created several shadow configurations, you can test them one by one to see the effects
of your changes.
The usual process looks like this:
1. User starts the crm
tool.
2. You switch to the configure
subcommand:
crm(live)# configure
crm(live)configure#
3. Now you can make your changes. However, when you figure out that they are risky
or you want to apply them later, you can save them into a new shadow configuration:
crm(live)configure# cib new myNewConfig
INFO: myNewConfig shadow CIB created
crm(myNewConfig)configure# commit
4. After you have created the shadow configuration, you can make your changes.
5. To switch back to the live cluster configuration, use this command:
