Hi
I'm trying to get a HA setup operational and am having issues.
I'm setting up 4 servers.
2 web servers and two db servers.
I have been trying to set them up all in 1 cluster so that I have
visibilty over all node statuses from one location.
i have grouped the web services (http, ip address and disk partition)
in 1 group and the db in another (mysql, ip and disk partition).
I am trying to enforce locations in the form of web group runs on
webnode1 or webnode2 only. db group runs on dbnode1 or dbnode2 only.
The Place consttraints I have are as follows.
<rsc_location id="webPlace" rsc="WEBstuff">
<rule id="prefered_webPlace" score="INFINITY">
<expression attribute="#uname"
id="ef686bfc-53ed-4910-84e1-8b08138bd83e" operation="eq"
value="portalweb1"/>
<expression attribute="#uname"
id="1527f928-c31e-46fb-abfd-02364e3684ea" operation="eq"
value="portalweb2"/>
</rule>
</rsc_location>
<rsc_location id="dbPalce" rsc="DBstuff">
<rule id="prefered_dbPalce" score="INFINITY">
<expression attribute="#uname"
id="1428c0c0-809e-4c26-ade6-5b0398843047" operation="eq"
value="portaldb1"/>
<expression attribute="#uname"
id="54853280-040b-4b64-99bc-f3570eb9999f" operation="eq"
value="portaldb2"/>
</rule>
</rsc_location>
<rsc_location id="noWebonDB" rsc="DBstuff">
<rule id="prefered_noWebonDB" score="-INFINITY">
<expression attribute="#uname"
id="52c7809d-c96a-4362-855d-27c1ac5e210a" operation="eq"
value="portalweb1"/>
<expression attribute="#uname"
id="2d8aa398-cdb6-473e-8c08-43305a78761b" operation="eq"
value="portalweb2"/>
</rule>
</rsc_location>
<rsc_location id="noDBonWeb" rsc="WEBstuff">
<rule id="prefered_noDBonWeb" score="-INFINITY">
<expression attribute="#uname"
id="4da1224c-5c59-4731-a507-6cfea7f408a3" operation="eq"
value="portaldb1"/>
<expression attribute="#uname"
id="b7470caf-8f54-42a9-9613-ab4ae7aa938a" operation="eq"
value="portaldb2"/>
</rule>
Looking at the hb gui currently I have the db services running on a web
server.... but I thought that should not be happening with what I have
defined.
I'm running hearbeat heartbeat-2.0.8-1 on FC6.
Any pointers greatly appreciated...
I think I could probably butcher this setup and have 2 seperate cluster
setups with 2 nodes in each but I would prefer to know why what I'm
doing is not working even if I have to go down that road anyway.
Thanks
Rafe
