[Pacemaker] How to add new resources to the production cluster

[Schmidt, Florian]

Hi list, 

It's my task to add a new resource (and also the corresponding drbddisk
and Filesystem resources) to our production cluster.

Is this the right way to do this on pacemaker 0.6.5-8.2:

cibadmin -Q > tmp.xml

edit the tmp.xml
	-add one resource group for both the drbddisk and Filesystem-RA,
just like I did it before
	- add one primitive for the main resource
	- add the collocation- and ordering constraints
	- increase the admin_epoch #

check the tmp.xml file with crm_verify

check the config with ptest and try to understand the .dot-graph ;)

reload the config into the cluster with cibadmin --cib_replace
--xml-file tmp.xml


Questions:
- tmp.xml contains both the config and the status section. Does this
cause trouble, when replacing the old configuration?
- do I have to increment the admin_epoch #?
- Is there a command to get both the resources-section and the
constraints-section (which I think are the sections you have to modify
mostly), without the status-section (something like cibadmin -Q -o
configuration)?

TIA
