[Linux-HA] cib.xml config problem

[Magnus Brown]

Hi Christian,

Thank you very much for your excellent reply.

With regards the gui problem, I was trying to create the clones inside
the group, which I think is incorrect, and hence why they were not
displaying correctly.

I made the syntax changes and added in the order statements and it seems
to be behaving as required. I've ust got to go through all the failure
scenarios to check its acting properly now :-)

I have included the working cib.xml if anyone needs to reference it,

Thanks once again,

Regards
Magnus

I have a quite similar setup.

Well, the GUI I used to configure clones (2.0.7 from RPMs) showed the
clones without any problems. Maybe you are using an old Version of the
GUI?

I created my cib.xml completely "by hand" - as I wanted to know
everything
the cluster is going to do - and understand how the config is built.  
(Well, some things I configured with the GUI and then took the
essentials
from the running CIB).

Ok, I checked your syntax and you can see the result in the attached
diff.
There were changes in the cluster-configuration and you were missing
some
ids and three attributes in the head. I didn't really "run" your
cib.xml,
but crm_verify -V just gave warnings about missing attributes in the
cluster-config, but no errors. You can ignore those warnings or just add
the values.

But I didn't saw any ordering in your config. Just Places where the
services have to run. You should go for the following entries in the
resource-section (maybe you should check this "order"-things the GUI):

<rsc_order id="order_ldapbeforeweblogic" from="ldap_clone"
action="start" type="before" to="weblogic_clone"/>

<rsc_order id="order_weblogicbeforefuego" from="weblogic_clone"
action="start" type="before" to="fuego_grp"/>

I don't know if the ordering itself is correct, but you may get the
trick 
with those rsc_order-Statements. There are some examples in the WIKI:

Happy Testing ;-)
