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
