[Linux-HA] Basic linux-ha questions

[Björn Boschman]

Hi,

I'm trying to build and test the following HA scenario:

* 2 nodes using crm

Using the following resources:

* DRBD8 as master/slave
* NFS server depending on DRBD

* Mysql master/master replication (only ip-failover)

* OpenSER active/hotstandby (only ip-failover)

* Maybe some more active/active with ip-failover services later on

Therefor I created the following resources and constraints:

http://prod01.nfon.net/~nfon/resources.xml
http://prod01.nfon.net/~nfon/constraints.xml

For testing purposes all resources are created with meta-attribute target_role=stopped.

SW versions:
* heartbeat 2.1.3
* pacemaker 0.6.5 (although there are several conflicts with existing heartbeat installation (duplicate files))

So now my questions:

1.
Would this in general make sense (also subjective meanings are welcome)

2.
When I start a resource with existing rsc_order dependency (e.g. mysql-ip) - should it start the dependend resources (override target_role)? Currently I have to set target_role=started for both resources.

3.
I wanted to test that configuration using CTS but I got several errors. Maybe someone can give me a hint on CTS test options, or some things to keep in mind (beside global syslogging which is already working)


If you need more input I can always put it online.

Thanks for any replies!
