Procedure
On each node:
- Shutdown Heartbeat
- Upgrade the Heartbeat program
- - This may also include upgrading the underlying operating system.
- Check the configuration manually or with the crm_verify tool if available.
- Start the Heartbeat program
Repeat for each node in the cluster
Notes
Always check your existing configuration is still compatible with the version you are installing before starting the first upgraded node.
- Versions 2.0.5 and later will actively enforce the DTD they ship with to prevent invalid changes to the configuration.
If you do not want this to occur, enable the ignore_dtd feature by setting it to true in the top-level cib tag.
<cib ignore_dtd="true" ... >
