[Linux-HA] Learning the CIB

Mon Jan 8 12:14:33 MST 2007

Ok, ok... Now I've fixed most part of the errors but I still theses and I'm
working on them for more them a hour now. Please take a look at them:

crm_verify[5457]: 2007/01/08_17:05:56 ERROR: Element cluster_property_set
content does not follow the DTD, expecting (rule* , attributes), got (nvpair
nvpair nvpair nvpair nvpair nvpair nvpair )

crm_verify[5457]: 2007/01/08_17:05:56 ERROR: Element primitive content does
not follow the DTD, expecting (operations? , meta_attributes* ,
instance_attributes*), got (instance_attributes operations )

crm_verify[5457]: 2007/01/08_17:05:56 ERROR: validate_with_dtd:xml.c CIB
does not validate against /usr/lib/heartbeat/crm.dtd
crm_verify[5457]: 2007/01/08_17:05:56 ERROR: main:crm_verify.c CIB did not
pass DTD validation
crm_verify[5457]: 2007/01/08_17:05:56 ERROR: main:crm_verify.c Triggered
non-fatal assert at crm_verify.c:242 : crm_mem_stats(NULL) == FALSE
Errors found during check: config not valid
  -V may provide more details

So... What's wrong here? According to the docs ( the cib-annotated ) there
isn`t such a thing ( or I haven`t read it correctly ) as:

<crm_config>
       <cluster_property_set>
           <rule>
               <attribute>
                   ( the nvpairs come here )
               </attribute>
           </rule>
       </cluster_property_set>
</crm_config>

I'm going to complete 150 lines of cib.xml and I still could't make it run
only once.
