Hello,
Happy New Year! This year I switched over to heartbeat 2. I like it,
but find the xml configuration file terrifying and ugly.
I was reading the heartbeat blog today and it got me thinking:
"This can be really annoying and can easily result in system
administrators[3] making mistakes either in the middle of the night,
or when under pressure"
I find managing the xml files with heartbeat 2 *horrible*. The
software is really nice, but every time I have to deal with xml I want
to poke my eyes out with a rabid shark.
The excellent haresources2cib.py script handles conversion of
haresources at the start, but all changes from then on need to be in
xml. The docs give examples, e.g.:
Here is an example of adding a resource to the CIB:
cibadmin -C -o resources -X '<primitive id="WebServerIP" class="ocf"
type="IPaddr" provider="heartbeat">
<instance_attributes>
<attributes>
<nvpair id="WebServerIP_ip" name="ip" value="127.0.0.26"/>
</attributes>
</instance_attributes>
</primitive>'
A few questions:
1. Without restarting or shutting down the cluster, and without
editing the cib.xml file how can I make a change to the cluster
configuration (i.e. how can I use haresources2cib.py to generate an
updated cib.xml and get the cluster to use it without a restart)
2. How can I override the defaults (such as timeout) in the resulting
cib.xml file?
Thanks a lot.
