I'am testing heartbeat 2.1.2 (using crm) and I have some questions
about resources.
My questions :
1)
I can see in traces (/var/log/ha-debug) lines like that :
pengine[6084]: 2008/01/15_13:42:00 notice: StartRsc:
anaisrh4-1 Start resource_ip_alias_eth0
others start resources ...
pengine[6084]: 2008/01/15_13:42:31 notice: StopRsc:
anaisrh4-1 Stop resource_ip_alias_eth0
others stop resources ...
My constatation is that start and stop orders are not respected in
the traces.
Is it normal ?
correct - ordering information is not listed in the log messages
What does this lines mean ?
that the resource will be both started and stopped
Is start / stop orders ar logged ?
yes
2)
"target_role" seams to be the future state to reach ;
yes
a dynamic variable.
no
In this case, why "target_role" appears into the CIB ?
because you can use it to tell what future state the resource should
be in.
ie. you can use it to tell the cluster _not_ to start the resource
3)
Is there any way to link 2 resources in order to initiate a failover
only if the two resources have failed.
not really
4)
On a resource failure on all nodes (the resource try to start on all
the cluster nodes before) is it possible to :
start failures are fatal - they prevent the resource from being tried
there again until the admin fixes the underlying problem and uses
crm_resource -C
- stop native resources or a resources group
- start other resources or an other resource group
?
The aim is to create fallback resources.
Thanks,
Sylvain
