[Linux-HA] clone constraints

Fri Jan 29 15:28:05 MST 2010

I have a new 2-node cluster I am attmpting to setup and I have run into
syntax issues with the constraints setion of the xml config. This setup
is a copy of a current cluster I have.

Both run rhel5 on proliant servers.

old setup:
libheartbeat2-2.99.2-8.1
heartbeat-resources-2.99.2-8.1
heartbeat-common-2.99.2-8.1
heartbeat-2.99.2-8.1
pacemaker-1.0.3-2.2
libpacemaker3-1.0.3-2.2

new setup(epel pkgs):
heartbeat           3.0.1-1.el5
heartbeat-libs      3.0.1-1.el5
pacemaker           1.0.7-2.el5
pacemaker-libs      1.0.7-2.el5
cluster-glue        1.0.1-1.el5
cluster-glue-libs   1.0.1-1.el5
corosync            1.2.0-1.el5
corosynclib         1.2.0-1.el5
resource-agents     1.0.1-1.el5

I attmpted to load the modified xml config from old to new and received 
errors :
root at wispoller2 configs]# cibadmin -V --replace --xml-file wispoller.xml
Call cib_replace failed (-47): Update does not conform to the configured 
schema/DTD

I then ran crm_verify -V --xml-file wispoller.xml and attempted to work 
through
resultant conflicts mostly by trial and error however when I got to the 
constraints
section I must admit I'm hooped.

Here are the last errors i recieved :

[root at wispoller2 configs]# crm_verify -V --xml-file wispoller.xml
wispollerv4.xml:98: element rsc_order: Relax-NG validity error : Expecting 
an element resource_set, got nothing

wispollerv4.xml:88: element rsc_location: Relax-NG validity error :

DTD/schema validation
Errors found during check: config not valid
[root at wispoller2 configs]#

Below is the complete config. The question is how can the clone 
constraints be rewritten to conform ?

In addition I had to change :
<rule id="stonith_rule01" score="-INFINITY" boolean_op="and">
to :
<rule id="stonith_rule01" score="-INFINITY">

to allow it to pass ...

Thanks
