[Pacemaker] Re: [Linux-HA] the crm command line interface

[Serge Dubrouski]

Hi, Dejan -

I just tried to use your tool for creating primitives and honestly
didn't like how it does it. Instead of typing a definition for a
primitive/group/clone/etc... in one line that includes all possible
attributes and operations I'd rather have a more interactive tool that
would guide me through possible choices. For example "primitive myIP
IPAddr" command could generate a generic XML template for a such
primitive and put it into vi/emacs editor allowing user to change
parameters and operations attributes. Or a set of interactive menus
with possible attributes and  operations that would allow user to
select necessary attributes and set values for them.

Then:

crm(live)configure# primitive myIP IPaddr params ip=192.168.1.130 op
start op monitor
crm(live)configure# commit
Call cib_create failed (-47): Update does not conform to the
configured schema/DTD
<null>
ERROR: could not create myIP
crm(live)configure#

But if I create ip.xml file like this:

     <resources>
       <primitive class="ocf" id="myIP" type="IPaddr" provider="heartbeat">
          <instance_attributes id="myIP_attributes">
               <nvpair id="myIP_ip" name="ip" value="192.168.1.130"/>
           </instance_attributes>
           <operations>
             <op id="monitor_myIP" name="monitor" interval="30s" timeout="30s"/>
             <op id="start_myIP" interval="30s" name="start" timeout="30s"/>
             <op id="stop_myIP" interval="30s" name="stop" timeout="30s"/>
           </operations>
         </primitive>
     </resources>

and then run cibadmin -R I'm able to create myIP but then your tool
complains like this:

ERROR: syntax error:
op start interval=30s timeout=30s
op stop interval=30s timeout=30s
