LS,

Now that I've got my cluster working, I'd like to be able to save the
config in SVN and to rebuild the cluster from SVN if necessary.

In a thread from 2007-076-14 I found a reference to this by Bron
Gondwana who wrote:

"Yeah, I have a couple of tools: 'update_managed.pl' which allows me to
mark nodes unmanaged, and 'scorched_earth.pl' which nukes all
heartbeat's processes on all nodes before it has a chance to figure out what's going on, then wipes out all on-disk config and state, builds and
installs the latest config from svn and brings everything back up
unmanged."

I'd love to see this scorched _earth.pl and hear how other people are
doing this because I'm not sure what to put in SVN, (obviously not the
entire cib.xml) and how to rebuild a cluster using SVN config files.

Yes, you should save the entire cib.xml, just without the status
section.

Which, luckily, is what the CIB stores on-disk :-)

That is the only way, unless you have some script
machinery to produce your production cib.xml.

Thanks,

Dejan

t.i.a!

regards,

Johan
